Preventing Algae in Swimming Pools

Whether you maintain your swimming pool yourself or hire a swimming pool service company to maintain your pool, you have more then likely experienced algae at some point.

Algae is caused from a variety of factors; so even a perfectly maintained swimming pool can have algae issues on occasions. In order to keep these outbreaks to a minimum there are three key elements to focus on which are circulation, filtration, and chemical balance.

  1. Circulation is very important to any swimming pool since stagnant water, even when properly balanced, can cause algae on the swimming pool surface. The more the water is circulated the less chance algae has to attach itself to the pool surface. So during warmer times of the year you should increase your pool filter time by a few hours per day or more to keep the water moving.
  2. Increasing the circulation time alone will not help unless your swimming pool has adequate filtration. Too many times filtration systems are sized at the minimum requirement and this places excess load on the filtration system very quickly.You want to check the size and type of your filtration system to ensure it is as large as you can reasonably afford to increase filtration effciency. This is one of those cases where bigger is better since a large filter will allow more water flow and greater debris trapping.
  3. Even if you have adequate circulation and filtration you must also keep your chemical balance within acceptable guidelines. If you do not keep chlorine levels, ph levels, alkalinity levels, etc. within guidelines your swimming pool will not have the sanitizing and oxidizing levels necessary to eliminate algae and other germs in the water.
