Why Is My Pool Water Green?

Learn why your pool water may be green.

A green pool is never a good thing to look at or swim in, but unfortunately, it does occasionally happen.  Whether opening to a green pool or in the middle of the swimming season, it can be fixed either by you or a pool service team. If your pool need maintenance, call Regina Pools & Spas today! Regina Pools offers a variety of pool maintenance packages all summer long, including weekly, bi-weekly, monthly, and on-demand packages. Read on to find out what happened as well as how to fix and prevent green pools.

What Happened?

Pools can turn green for a variety of reasons. Some of these include improper filtration, lack of chlorine or an algaecide, chemical imbalance, or even weather. If your filter is not running enough during the day or there is something wrong with the equipment, the water may become stagnant and even proper chlorine levels will not be able to stop algae from growing. If the chlorine drops below 1 ppm; your pool is no longer sanitary, leaving your pool susceptible to an algae bloom. As well as low chlorine, balance levels such as ph and alkalinity need to be checked to make sure they are not affecting chlorine adversely. Not to be forgotten is weather. The sun will burn off chlorine and the rain will dilute all of your chemicals. For all of these reasons and more, it is very important to get your water tested regularly to ensure algae never gets a chance to start.

How do I fix it?

When trying to clear a green pool, be sure to bring us a water sample before trying too many things. Sometimes, there can be something causing a normal treatment not to work. Also, in store, we can give much more detailed instructions to make the pool treatment that much easier on you. Below are some steps that may be needed to help clear the pool up.

  1. Removing as much debris as possible. When you add chlorine to a pool (or shocking the pool) with leaves and dirt in it, the chlorine gets used up trying to destroy that matter instead of clearing the pool. Help your chlorine to work harder by clearing out as much as you can beforehand.
  2. Before shocking your pool, make sure the filter is running, and test the chemicals to ensure the alkalinity is between 100 ppm and 150 ppm and the pH balance is between 7.4 and 7.6. A properly balanced pool will allow the chlorine to work harder and faster. As a side note, the shocking process should be done at night.
  3. Once the pool has been shocked, you will need to add an algaecide meant to kill algae.
  4. Brushing will also be a very crucial step in fighting algae. Algae will root itself to the surface of the pool and not come off unless repeatedly brushed. With chlorine and an algaecide in the water to kill it while the algae’s surface has become unprotected by the brushing action will make this process go faster.
  5. For some pools, repeating this process may be necessary. Different types of algae can react differently to treatments.

How can I stop this from happening again?

After fighting a green pool, there are several things you can do to ensure it doesn’t happen again. First and foremost is regular water testing. Cyanuric acid, or CYA, is added to water to stabilize the chlorine, protect chlorine from UV rays, and help free chlorine levels last a long time. If CYA levels are low, the sun will dissolve the chlorine, which will cause you to add chlorine more often.  A maintenance dose of an algaecide will also help prevent algae from growing.

Bioguard’s Optimizer Plus is an EPA registered algae suppressant that stops algae before it starts to grow. This is added once and only topped off occasionally. Bioguard also offers other fantastic products to make sure your water remains clear and never cloudy as well.
