How to Clean Your Pool Cover

GLI ProMesh Safety Cover.

When Credible Pools opens your pool at the beginning of the season, we spray off dirt and debris off of your cover before we remove it. If you want to scrub it before leaving it to dry and storing it away, we have some tips to help you do that.

After we have finished removing your cover and opening your pool, we will leave your cover in the location of your choosing so you can clean it. We will have removed the big debris from the cover before removing it to ensure that everything you have been protecting your pool from over the winter doesn’t fall into your pool.

It is not entirely uncommon to see mold on your pool cover. A mesh pool cover allows air and water to pass through, so they do not collect a great deal of mold. (Which is why we love GLI ProMesh safety covers.)

Cleaning

To clean the cover, it is best that you lay it out as flat as possible in a clean section of your yard. To clean your cover, you could use a mild detergent diluted with water or a spray-on pool cover cleaner.

If your cover is full of dirt and grime, you will need to scrub it with a pool cover brush or something similar, like a push broom. Never use any type of metal brush on your cover.

Be sure to rinse your cover thoroughly and be sure that all of the detergent, soapy water or cover cleaner has been removed completely. You do not want these cleaning agents sitting in the fibers of your cover.

Drying

Once clean, it needs to dry. Your cover must dry completely before you can put it into storage. This will prevent any mold or mildew from growing on your cover as it is locked away over the Spring and Summer months.

Move your cover into the sun. Laying it flat in your driveway or hanging it over a clothesline are the two best ways to make sure the entire cover can drain and dry. Leaving your cover to dry on the grass will take much longer and may potentially harm your lawn and kill your grass. You want people to notice your pool, not the giant patch of dead grass in your yard.

Storing

To store your cover, it is best to fold it in half over and over again, or a “fan fold,” until it is small enough to fit inside the storage bag that came with it. You may need a second set of hands for this task.

We recommend a secondary storage step; one step further than just the bag, but this is optional. It’s a good thought to either hang the bagged cover up high or to put it in a large container and lid. A large Rubbermaid container or a large trash can with a lid will do. This is to make sure that no creatures find their way into your cover and burrow there over the next few months.

All of this will help keep your cover in good shape and is ready to go at the end of the pool season when it’s time to reinstall it. If cared for properly, we’ve seen pool covers last nearly 20 years.

Are you considering replacing your current cover? Now is a good time to put that plan into action. Ordering a new winter cover early in the season will get you ahead of the rush and ensure that you will be prepared when pool season comes to an end.

Different Types of Pool Covers

Proper protection for your pool in the off-season is extremely important. Credible Pools is based in southwestern Pennsylvania where we can potentially see significant snowfall. We’ve already seen more snow this winter than we’ve seen in the last few years with a real chance of seeing even more. Unfortunately, we got quite a few calls about the damage the recent snow accumulation has done to some pool owners’ covers.

We want to take this opportunity to teach you about different types of pool covers, how they hold up throughout the winter, and furthermore, why we strongly recommend and only sell Commercial Grade Mesh Safety Covers.

Standard Covers

Just a standard pool cover is made of a cheap, tarp-like material and is held down by water bags, which are inconvenient and take a lot of time to fill.

This type of cover offers next to no protection. It will keep sunlight and small debris out of your pool, but it can only hold very little weight. This poses a real risk if you have children, pets, animals that visit your backyard, or anyone around the pool in general. They can easily fall into the pool and the cover itself poses an entrapment hazard.

This type of cover requires the pool owner to remain vigilant throughout the fall and winter of any accumulation on top of the cover. An additional pump is necessary to remove any water that collects on the cover. The pump will do nothing to remove any snow. It won’t take much to damage the cover or cause it to cave in, so snow and water removal must be done diligently.

A standard cover will only last one to three seasons. The pumps usually last only two to four seasons. It’s not a sound purchase, especially in areas that see a lot of rain and snow. Lastly, it’s an absolute eyesore.

Automatic Covers

Automatic pool covers are made of a vinyl material and require an entire mechanism of pulleys, tracks, motors and more. They give you the convenience of covering your pool whenever you want or need just by turning a key.

We want to be clear – Automatic cover, or Autocovers, are NOT a winter covers. They are simply not designed to hold heavy snowfall. This can cause equipment damage that is costly to repair.

Automatic pool covers can be expensive, both initially and throughout their lifetime. The vinyl material typically wears out in about five years. With so many components involved in the entire mechanism, there more potential for parts to break down. Autocovers also require an additional pump to keep water off the top.

These covers are great to use day-to-day during the pool season. They can help leaves out of your pool to help make your regular cleaning easier. They are also good for keeping heat in, giving your pool heater a break. They are simply not a winter cover.

Solid Covers

Solid covers are composed of a single, solid piece of material, typically vinyl. They allow nothing to pass through them into your pool throughout the winter months.

Compared to mesh, solid covers requires a more involved installation, a more difficult removal and additional concerns when it comes to storing them during the season. Since they are one solid piece that doesn’t really “breathe,” any moisture on or in your cover will mold while in storage.

The lifespan of solid covers isn’t ideal and they typically only last about 7 to 10 years if you’re lucky. They also require an additional pump to remove any rainwater that collects on top of the cover. Pumps typically last about two to four years.

Solid covers require constant maintenance in the off-season to protect it from accumulating too much water or snow. This weight causes the cover to sag and really shortens the life of the cover.

Overall, we just don’t see these as being a reasonable option when you could get as much protection, a longer warranty, and much less hassle from a mesh safety cover.

Standard Mesh Safety Covers

Standard mesh safety covers are made with a woven, polypropylene mesh material. They will let some light through vs a solid cover, which can cause additional algae growth through the winter.

They are held by anchors that are drilled into the concrete around your pool and metal springs to provide great protection from debris during the off-season. The mesh material allows water to drain right through so you don’t have to worry about any accumulation on top of the cover.

While this type of cover will provide a basic level of protection, they do not live up to the standard that we want to sell to our customers. Unless your pool will be completely undisturbed during the winter months, we just can’t fully recommend a standard mesh cover.

Commercial Grade (ProMesh) Covers

The step up from standard mesh is GLI’s ProMesh Safety Covers. They’re woven tighter, achieving nearly 100% light blockage, so you do not have the algae growth and they are stronger than standard mesh. The heavy duty commercial grade springs allow the cover to flex under the heaviest of snow loads. The extra strength material provides greater tear resistance and tougher winter wear-ability.

We added this brand new GLI ProMesh Safety Cover to a customer’s automatic cover.

These covers offer almost 100% protection from UV light, preventing any algae growth in your pool, making your pool opening a breeze.

If you have children, pets, rain, or snow and want a longer lasting cover with a better warranty, we strongly recommend GLI’s ProMesh Safety Covers.

These covers are known to last up to 15 years and beyond. In terms of safety, protection, longevity, and cost, these are the best in the industry.

Chlorine vs. Salt Water Pools

Keeping your pool water sanitized and maintaining proper chemical levels will be your biggest responsibility as a pool owner. The two main options you have to sanitize your pool are the traditional chlorine method or a salt water system.

Your choice will mostly depend on your level of commitment to your pool, and whether you’re prepared to make a large initial financial investment or would rather spend less money at first but put money toward your pool continuously over time.

Let’s break the two systems down a little bit.

Chlorine

A chlorine pool system is cheaper to install – the initial cost is much lower. All you really need is just the pump system and a device to chlorinate your pool. A floating chlorinator is the device most commonly recommended and used. You simply fill it with chlorine – which can come in stick, tablet or liquid form – based on the size and needs of your pool.

Initially, this may seem like the most reasonable option, but the real cost will add up over time.

The chemical levels in your pool water will be much more unpredictable, should you opt for chlorine. You will have to regularly, habitually pay attention to the levels, requiring you to test your water at least once daily.

Chlorine is corrosive. It can be harmful to your hair, eyes and skin, especially if you do not properly maintain your chemical levels. High levels can damage equipment and eat away at you deck paint. It can cause the fabric of bathing suits and towels and the material of your liner and pool toys to fade due to chlorine’s bleaching properties.

Chlorine rash can result from swimming in a pool with chlorine levels that are too high. While not fatal, medical treatment is necessary if it doesn’t clear up on its own.

You will have to factor the cost of regular chlorine purchases into your budget for the entire life of your pool. This adds up and in the long run, can end up costing you so much more – hundreds and hundreds of dollars a year.

That does not take into account that sunlight, rainfall, temperature, number of swimmers, and frequency of pool use all affect the rate that the chlorine will dissolve. These factors will drive up your chlorine usage, thus unpredictably increasing your cost each year

Salt Water

A salt water pool does not mean chlorine free. Your pool water will be chlorinated and sanitized in a different way.

A salt-chlorine generator includes a salt cell. The salt you add to the salt cell goes through “electrolysis.” This process produces just enough chlorine to meet your pools needs, based on how many gallons of water your pool holds.

The upkeep that you’ll have to worry about the most is simply adding salt when the levels go below the unit’s operating range. Again, this varies from pool to pool, but your pool professional will inform you of the proper level for your pool.

Salt is much gentler on your skin, hair and eyes. It won’t fade your fabrics, damage your liner or eat away at your deck paint.

Your annual maintenance cost will be lower since you won’t have to constantly buy chlorine.

Where the main cost lies is in your initial investment. The price upfront is indeed mich more than a traditional chlorine pump system. A salt water system is more complex and repairs can be a little more complicated. This type of system also requires more power and will add to your electric bill noticably.

Salt cells much also be cleaned and changed periodically. You will have to check the cell for calcium deposits.

In conclusion…

It all comes down to if you have the money to spend now on an initially more expensive system OR if you are willing to put in more daily work and are able to factor in a constant long-term expense to maintain your pool while spending much less up front.

Pool Tips

Do NOT Add Chlorine to Your Skimmer

While putting chlorine directly into your skimmer may seem like an easy way to sanitize your swimming pool, THIS IS A BAD IDEA.

Your skimmer is designed to keep your pool free of debris.  The suction from your pool pump siphons water through the hoses connected to your skimmer.  The water is then routed through your filter and clean water is pushed through the return jet of your pool. 

Adding chlorine to this sounds like a good way to add it to your pool water, right? 

Wrong.  This does far more harm than good

– especially if you’re not running your pump 24/7.

With the pump off and no water flowing, the chlorine tablets will sit inside the skimmer and dissolve slowly.  What you’ll end up with is a rich, extremely acidic amount of chlorine that can eat away at the skimmer walls and the basket.

Chlorine Tablets in Pool Skimmer

This line was so full of chlorine that it collapsed.

The longer it sits, the more damage it does as it clogs up and eats away at the hoses.

Chlorine Tablets in Pool Skimmer

This skimmer line needed completely replaced. This job took about 10 hours to complete over two days.

You can save yourself so much work, damage, money and headache if you just sanitize your pool properly. 

It’s so easy to do!

The simplest solution, if you decide chlorination is the way to go, is to purchase a floating chlorine dispenser.  All you do is fill it with chlorine tablets and let it float around your pool. You can also plumb in an off-line chlorinator (we do not recommend in-line) specifically designed to house tablets.

The BEST option is to switch to a salt water system which makes caring for your pool as easy as possible.  Salt water pools require less maintenance, provide softer water, and are more cost effective in the long run.

Tips for Keeping Your Kids Safe Around the Pool This Summer

by Alex Robbins

Swimming pools provide all kinds of benefits for kids. Not only are they a great source of exercise, but they also offer hours of entertainment and an excellent place to spend quality time with family. But pools can also be dangerous. It’s important that parents take steps to secure the pool against accidents and teach their kids how to be safe around water. With some good swimming skills and safety equipment, your family will be able to splash away all summer!

Upgrade Your Pool

Pools are hotspots for summer fun. So, make sure your pool and the surrounding area are in good condition to prevent accidents.

  • Is your pool showing signs of age? Start budgeting for a pool repair now!
  • If you need a new pool filter, switch to a DE (Diatomaceous Earth) filter for cleaner water.
  • Make your swimming pool deck less slippery with textured concrete or pavers.
  • Prevent sunburns by shading a portion of your pool and deck with a canopy or gazebo.
  • Since chlorine can irritate the skin and eyes, make sure you take steps to lower the chlorine levels when kids are swimming.
Build a Proper Fence

Ensure your pool is fenced off from the rest of your home so kids can’t fall in accidentally.

Teach Your Kids to Swim

Helping your kids develop strong swimming skills will keep them safer in the water.

  • Make sure your kids have the right gear before introducing them to swimming.
  • One of the first swimming skills your kids should learn is how to float in the water.
  • If your kids are interested, swimming-based activities can strengthen their skills.
  • Teach your kids safe swimming practices to prevent accidents in the water.

Don’t spend your summer worrying about the safety of your kids in your backyard pool. Your pool should be a place of fun and relaxation! Take the time to make safety upgrades to your outdoor oasis and teach your kids to be strong, safe swimmers, and you’ll be able to enjoy it too!

Frequent Questions

DE vs Sand and Cartridge Pool Filters

What filter should you get? Ask yourself these questions:
  • Would you like your water as clean as possible?
  • Would you like to not have to disassemble your filter?
  • Would you like the easiest way to clean your filter?

The answer to these questions is DE (Diatomaceous Earth) Pool Filters and why we recommend them. Honestly we cannot figure out why any other filters are installed other than for initial cost or to generate repeat purchasing of cartridges. In DE Pool Filters, The DE powder is mixed into the filter and coats a filter “grid”, which then collects particles when your pool water is run through the filter. This powder is finer than sand or cartridge media. Therefore, a DE pool filter can filter out the smallest particles, down to 2-5 microns. Sand filters get somewhere between 20-100 microns and cartridges capture 10-15 microns. That means that DE filters provide up to 50X TIMES more filtration than sand and 7.5X TIMES more filtration than a cartridge. For us, the choice is simple.

Maintaining a DE filter is just a simple backwash procedure outlined here. DE filter powder is also very inexpensive so they pay for themselves in a very short amount of time compared to cartridges. We carry Pro-Grid Filters from Hayward with a 3-year parts & labor warranty. You will see a water quality difference if you choose this type of filter and have had a cartridge or sand filter on your pool. The water will be clearer and some even describe it as being polished!

Glass Media in a Sand Filter

If you have a sand filter and do not want to replace your filter, Glass Filter Media is a great option. We still like DE better, but Glass will filter down to roughly 5-10 microns.

Sand media needs to be changed out every 3-5 years depending on the water and debris load that is going through the filter. Glass media lasts about 2-3 times as long as sand filter media.

Frequent Questions Pool Liners

New Pool Liner Installation

When you get a new pool liner installed for your in-ground pool, you probably will have some questions. A new pool liner will immediately make an older pool look new, plus it is an opportunity to change the color. It can even feel like a brand new pool even though it is just new vinyl. Our pool liner manufacturer is GLI and you can check out their colors and options here.

Every pool liner is custom made and needs to be precisely measured. You can schedule a measurement by booking an appointment. Or just pay for a measurement and we will get in touch to schedule. The price of the measurement will be taken off the final price if you purchase it from Credible Pools. The same goes for pool safety covers. We are free-form liner specialists, and free-forms are the hardest to measure for both liners and pool covers. Free-forms are also more expensive than a typical square or rectangle shape.

Once your pool is measured and the liner is ordered, the process to actually manufacture it is usually less than a week. Installation will be scheduled once it is received. The pool is drained with a pump and the old vinyl is cut out. At this point, there may be additional problems discovered and more work that needs done to repair walls and the bottom of the pool. After that our liner experts will hang it and vacuum it and begin filling the pool with water from a truck to set it in place.

A Note about wrinkles and imperfections

We do the absolute best job we can measuring and installing, and we rarely get wrinkles. They can occur though, but often we are at the mercy of how the pool was installed originally. The thickness of the liner also contributes to the ability of it to stretch and conform, so a thicker liner (28 mil) can actually end up with more imperfections in the end (so we normally recommend 20 mil depending on the pool shape). It is also not uncommon as the new pool vinyl sets and conforms in the first season for it to occasionally pop out of the track along the top of the pool which may also be affected by the existing bead receiver. The age and condition of the pool plus shifting and settling that happens over the years can also cause things to not be ‘perfect’ and perfection simply cannot be guaranteed with a new liner.

Frequent Questions

Electric vs Gas Pool Heaters?

The following information and recommendations are based on over 25 years of experience in pool installation and maintenance in Western PA

Electric pool heaters (Heat Pumps) cost more than gas pool heaters, but they are generally more efficient and cheaper to operate. With proper maintenance, electric heat pumps typically last longer than gas pool heaters. Electric heat pumps are essentially an air conditioner in reverse. They are also larger in size and heat much slower than a gas heater. Electric heat pumps work efficiently as long as the outside temperature remains above the 45ºF–50ºF range. Recommendations are situation dependent based on service availability and a number of other factors. For certain customers, heat pumps are a great option to consider.
Pros: Lower operating costs, environmentally friendly, lasts longer
Cons: Requires warmer ambient temperatures, higher initial cost

Natural gas heaters are able to maintain a constant water temperature in any weather conditions and heat water much faster. We do not recommend propane. If you want to keep your pool warm when it is colder (below 55ºF), then gas is your best option. If you OVER-size a gas heater you can get your pool to temperature quickly and with decent efficiency. Again, dependent on a number of factors, we often recommend gas heaters to customers if an adequate gas supply line is available.
Pros: Heats pool quickly, lower initial cost
Cons: Higher operating costs, generally fails sooner
