How To Prevent Algae From Forming In Your Pool
The best algae treatment is prevention. Here are some helpful tips to keep algae out of your pool in the first place.
- Algae thrive in pools with unbalanced chemical and pH levels. Check your chemical levels at least every few days. Use testing strips to measure the chemical and pH balance of your pool.
- Ensure that your filtration system is working properly. Uncirculated water can be a breeding ground for algae. When treating your pool for algae, run the filter system continuously. Remember to thoroughly clean your filtration system to prevent the buildup of algae-attracting debris.
- Use your pool. Active water is cleaner water. Stirring up the water in your pool will help you to keep it clean and bring any standing dirt and debris to the surface. This is a great way to prevent algae from forming in the first place.
- Cover your pool when its not in use. Consider adding an automatic safety cover that will keep your pool free of dirt particles, which attract algae and help it spread. Wind and rain also carry contaminants that affect the chemical levels in your pool, making an algae infestation more likely. Regularly clean your pool to keep dirt and debris from gathering at the bottom of your pool.
- The use of algaecides can prevent algae growth.
Pools are a great source for relaxation or family fun, but without proper maintenance algae can quickly take over. Creating a basic plan for algae prevention will keep your pool clean and healthy all year long.
Cleaning Algae From Swimming Pools

How Is Algae Prevented
Proper chemical balance and sanitizer levels will prevent many opportunities for algae to bloom. High pH and low chlorine can give algae a great start. Using cyanuric acid to protect your chlorine from the sun has the added effect of suppressing chlorine activity, giving algae opportunity to bloom, unless chlorine levels are increased.
General cleanliness of the pool is also important. Organic material and bacteria contribute to algae growth. Regular brushing of seemingly clean pools is not only good exercise for you, but prevents dirt from harboring in the pores of the plaster, which is a good start for an algae colony.
Using specialty chemicals or algaecides is recommended to provide a back up to normal sanitation and filtration processes and is necessary for many pools. These chemicals are described below: âProper Filtrationâ is a term we throw around a lot, and it refers to quantity and quality of filtration. Most pool filters should run for a minimum of 12 hours per day, or longer if the pool filter is undersized or the filter media is old and not as effective as it once was. Poor circulation can also play a role, especially for larger pools with inadequate plumbing or pump size. Using an automatic pool cleaner can help circulation immensely.

How To Prevent Algae In Your Pool
Following these basic pool maintenance principles will help prevent future algae issues.
- Test and balance your water once a week, after rainstorms, or after heavy use . Adjust your alkalinity, pH, and chlorine levels as needed
- Shock your pool once a week during peak pool season
- Run your pump 8 to 12 hours per day to fully circulate your water
- Clean or backwash your filter regularly
- Wash and sanitize your swimwear, pool equipment, floats, and toys before introducing them back into your pools
- Add flocculant or algaecide if you notice the early stages of algae growth
Getting Rid Of Algae By Adjusting The Water Ph
An important first step to getting rid of algae is testing and adjusting the water pH in your swimming pool. The water pH changes over time with the weather and other conditions, causing algae to bloom, and its essential to adjust it accordingly.
- Muriatic acid
Purchase a test kit from your local swimming supply store or online and test your pool water at least once each week, and more often when it rains and with frequent use.
Take a water sample from 12 to 18 inches below the water surface and test it for calcium, alkalinity, and sanitizer. A good range for calcium hardness is 200 to 400 ppm, with an alkaline level of 80 to 120 ppm and a chlorine level of 3 ppm.
Adjust the pH level, so it falls between 7.4 and 7.6 ppm by adding soda ash to increase and stabilize it or muriatic acid to lower it.

Causes Of Algae In Pools
Why is algae in the pool or what causes algae to grow? Cyanobacteria algae occurs naturally, and is contained in nearly all soil and plant debris. Algae spores can also blow into the pool, or can even be introduced by contaminated ocean swimwear. In short, algae are always in the pool, and can bloom into a visible colony when conditions are right:
- Poor water circulation low flow or dead spots in the pool
- Poor water balance pH, Alkalinity, Calcium and Cyanuric levels
- Poor water sanitation low or inconsistent chlorine levels
- Poor water filtration short filter run times or an ineffective filter
Any combination of the above factors can allow algae to take a foothold, sometimes in just a few hours on a warm summer day. Using a high quality pool algaecide regularly can provide insurance against those inevitable problems that cause circulation, filtration or sanitation to drop below critical levels.
What Happens If You Dont Reduce Phosphate Levels
If you notice higher phosphate levels, it is necessary to deal with the issue as quickly as possible. High phosphate levels can lead to a lot of other issues such as these:
- Phosphate acts as food for algae and other aquatic plants. With high phosphate levels, these can grow more and eventually cover your pool.
- Phosphates also reduce the efficiency of chlorine in cleaning the water. With more organisms growing in the water, the chlorine added has a tougher task at hand and might not be able to keep up with the growth.
- As chlorine usage increases, you will have to regularly check and maintain the chlorine level in your pool. This makes pool maintenance a very demanding task and also expensive.
- Phosphates also combine with calcium to form calcium phosphates scales. These settle on the surfaces of the pool as well as any pool accessories like steps or stairs and damage those surfaces.
