In other words, the more you run your filtration system, the cleaner your water will be – and the less time you’ll have to spend scrubbing algae or balancing your water. If running your filter 24/7 isn’t realistic, aim to run your pool filter 10 to 12 hours per day. If you are in a warmer climate, you should run your pump a little more per day. This is why we suggest investing in a variable speed pool pump because they can run at a lower speed throughout the day, which saves money, energy, and makes less noise.
If your pump gauge is about 10 lbs or more above the normal reading (usually 10-15 psi for a clean filter), then it may be time to backwash your filter. If you are using a cartridge filter, then you will need to clean your filter cartridge.
Cleaning the skimmer and pump baskets regularly is important to the overall maintenance of your swimming pool. Clogged baskets make your pump work harder to try to cycle the water. This can decrease the life and stress the seals in your pump. Additionally, critters like frogs can get stuck in your skimmer, so you will want to make sure those are removed in a timely manner as well. We suggest cleaning your skimmer once or twice a week depending on how often you use it.
Every once in a while, you should also clean out the pump basket on your pool pump. You don’t have to do this as often since the skimmer catches most of the debris.
Another easy adjustment to make is to make sure your pool jets are pointing away from your skimmer so that your water cycles in a circle. This will encourage the pool water to rotate and make it easier for your skimmer to get rid of debris. It also helps to angle the jets downward so that the bottom of the pool gets circulation as well. If there are any parts of the pool that struggle to get water, most commonly the around the steps, ladders, crevices, and corners of your pool, you can angle towards these areas too.
The next step in the trifecta of pool maintenance is cleaning which comprises brushing your pool, skimming the debris off the top, and vacuuming the pool. Manual maintenance is a normal part of pool ownership unless you own a robotic pool cleaner which will do it for you.
Skimming the surface of the water with a net or leaf rake removes large debris. This debris is unattractive to swimmers and can fall to the bottom of your pool where it can leave stains.
Vacuuming your pool is another essential part of removing debris that can reduce circulation and damage your pool. You can use a vacuum head, hose, and pole attached to your skimmer through a vacuum plate. Click here for a step-by-step guide to vacuuming your pool.
Chemistry is another huge factor in keeping your water clean. When your water is properly balanced, you’re less likely to struggle with issues like cloudy water, green water, or buildup of harmful bacteria. That’s why a good testing kit is an essential for your pool maintenance toolkit.
For best results, test your water weekly. To keep things easy, opt for a test kit that will tell you if you need to add pool chemicals to maintain your water balance. Most pool supply stores and big-box retailers sell easy-to-use test kits or test strips that allow you to test your swimming pool water for the key chemicals. Here are the essential ranges to keep in mind:
pH: Ideally, you want your pool water to have a pH of around This is important because pH levels that are too high or too low can lead to a variety of pool maintenance issues, from equipment corrosion to increased green algae growth. See our pH guide
Calcium hardness: Again, it’s all about balance here: Shoot for 200 – 400 ppm in a pool. When calcium hardness levels are too low, you risk damage to your pool’s plaster finish or vinyl liner. But if your pool’s calcium hardness is too high, you’ll be scraping away tough-to-remove calcium deposits. See our calcium hardness guide
Alkalinity: You want to aim for a total alkalinity of around 120 to 150 ppm. If it’s below this range, your pool’s pH can be affected, and your pool’s surfaces are more prone to stains. If it’s on the higher side, your water can become cloudy. See our alkalinity guide
Chlorine: Available in sticks, granules, and tablets, chlorine breaks down harmful bacteria and sanitizes your pool water. You’ll want to keep the chlorine levels stable to ensure that your pool stays clean. See our chlorine guide
Phosphates: If your pool water is green and cloudy, it is possible that the phosphate levels in your pool are too high. Having too many phosphates in your pool can make algae growth more likely and makes it more difficult to maintain proper pool chemistry. See our phosphates guide.
In addition to keeping your pool chemistry balanced, it’s also a good idea to shock your pool once every week or two. “Shocking” means you overload your water with sanitizer to kill off any bacteria, contaminants, and organic matter. For more information, learn how to shock your pool in 6 easy steps.
In general, the more you use your pool, the more often you should shock. You may also want to shock your pool after periods of heavy use or weathering in these cases:
If you follow these basic steps, you will be on your way to maintaining a crystal-clear pool and avoiding problematic algae growth. The key is establishing a routine and taking early action if you notice discoloration, cloudy water, scaling, or other signs of trouble. And if you ever find the responsibilities overwhelming, a Pool Service Professional can take care of your pool for you. For a reasonable price, they’ll visit your house every one or two weeks and take care of all the of this stuff for you!
Algae growth is perhaps the most obvious sign of something gone wrong with pool maintenance. Proper maintenance will not only keep your water looking great, but also allow for easy prevention of algae growth. When preventative measures aren’t enough, you’ll need to remove the algae to get back to enjoying your swimming pool.
Gold CoastFree-floating types including green and mustard varieties. These tend to be found throughout the water. Mustard algae tends to cling loosely to the walls of the pool and brushes off easily. It tends to have a yellowish color. Green algae will be visible throughout the water itself and will turn the water different shades of green depending on the infestation.
Black algae is the common name or term given to the dark blue-green algae found growing on pool surfaces. Black algae grows in localized areas such as along one wall, in the deep end, in a corner or around obstacles such as steps indicates an area of poor circulation and poor sanitization.
The growth of both types of algae can be easily prevented by using a quality algaecide as part of a regular maintenance program, and by proper circulation. It takes far less algaecide to prevent algae growth from getting started than it will to cure it once it has occurred.
The regular use of algaecide is also recommended to prevent problems should a failure of the sanitization program occur. Due to the unique nature of chlorine or bromine, these residuals can often be lost very quickly in pools due to equipment or operator error or by heavy rainfall or bather waste demand. Improper water balance will contribute to the ability of your sanitizer to work properly and prevent algae growth. If this occurs without an algaecide present, the rapid growth of algae can occur in a few hours. However, if an algaecide is present, it will act as algae growth prevention (look at it as an insurance program) until the sanitizer system is functioning normally.
In spite of your best efforts, algae problems can occur and require some consideration for proper treatment. When an algaecide becomes necessary, read our guide to pool algaecide types to find your perfect product.
The most common cause of algae growth in a swimming pool is chemical imbalance. If you’re not keeping up with routine maintenance -- including vacuuming your pool and testing and balancing your water -- you’re more likely to struggle with algae issues. And, as any swimming pool owner can tell you, it’s much easier to prevent algae than to try to remove it with pool algaecide.
The most common algae associated with swimming pools is green algae. It is very opportunistic, meaning it will take advantage of any failure in the normal sanitizing program and quickly infest a pool. One will see green algae problems frequently appear overnight following heavy rainstorms. This is because rainstorms actually provide food for the algae in the form of nitrogen. The nitrogen not only feeds the algae but also destroys chlorine residuals.
Green algae must not be mistaken for metal present in the pool water. Metals, especially copper, can give the water a clear green tint. The best way to treat green algae is to prevent it in the first place. Use an algaecide regularly as part of a normal maintenance program. This will prevent algae from growing, even if a failure in the sanitizing system was to occur. It is always easier and more effective to prevent the algae problem than to try and eliminate it once it occurs. When it does occur, treat it promptly. The longer you wait before treatment, the more difficult and costly the result. Select an algaecide that will both kill the existing algae and prevent renewed growth. Follow the label directions and maintain circulation during treatment.
Scrub (again) and vacuum. Take a second pass with your pool brush to remove any remaining green algae. Follow up by vacuuming your pool. This will remove any dead algae that has collected at the bottom of the pool.
Yellow or mustard algae is very similar in form to green algae, but is much slower growing and is deficient in chlorophyll (green pigment) which accounts for its yellow color. It is easily identified by the ability to brush it easily off the pool walls and floor. Because yellow algae grow very slowly, it is also very difficult to destroy. By the time you see it growing in your pool, it has likely been there as long as several weeks. Additionally, since yellow algae is low in chlorophyll which is light-loving, the algae live and even grow in dark areas of the pool such as plumbing and filters. This only compounds the difficulty of control.
To treat mustard algae, care in selection of a proper algaecide is most important. Be certain to select a product made for the control of this unique form of algae. Copper-based algaecides seem particularly well suited for controlling yellow algae. One word of caution: it is not unusual to need to treat yellow algae more than once to bring it fully under control. This again points out the value of preventing the growth in the first place.
Clean everything that has come into contact with your pool water. Wash swimsuits and towels (use bleach!), and make sure to clean and disinfect pool toys and equipment. Remember, yellow algae spores can survive on almost any surface, so this step is critical!
Scrub and vacuum your pool. Use a good pool brush to scrape yellow algae off of your pool walls. Once you’ve removed all of the algae, vacuum your pool thoroughly.
Test and the water. If anything is out of balance – say, the pH is too high or the alkalinity is too low – add chemicals to bring things into line.
Shock your pool. You'll need to use around three times more shock treatment than you'd use for green algae. Run your pool filter for at least 24 hours to ensure that the shock treatment can circulate.
Repeat steps 3, 4, and 5 as needed. Test, brush, and shock your pool as needed, until your pool is 100% algae-free and your water chemistry is balanced.
