How to get rid of Algae in a pool

Here you will find step by step instructions on how to turn a green pool back to blue and crystal clear. This process can vary from 1 - 5 days depending on several of factors including: pool size, filter type, filter size, and time you put in. Before starting this process, ensure that your pH is in range of 7.2-7.8 and that your filter is clean.

  1. Vacuum up as much of the algae as you can see.
  2. Thorouhly brush the entire pool, including the bottom, walls, steps, and behind any ladders. Sometimes it is easier to take the ladder out to really clean behind it.
  3. Add a troubleshooting or algae removal does (see product label) of an Algaecide with the active ingredient: Poly[oxyethylene(dimethyliminio)ethylene (dimethyliminio)ethylene dichloride] 60%. There are many different strengths of algaecide, but you are better off using a higher percentage that will not cause foam.
  4. Wait one hour. Shock the pool with either powder shock (with an active ingredient: Calcium Hypochlorite 73%) or ligquid shock (with an active ingredient: Sodium Hypochlorite 10%).
  5. Maintain a high chlorine for at least 24-48 hours or until the water turns blue and cloudy. If chlorine tests under 10ppm, repeat shock dose.
    Remember to backwash or clean your filter if the pressure rises 8-10 psi over your starting pressure. You might have to do this multiple times.
  6. Once the pool is blue and cloudy, add a water clarifer (see label for dosage). If the pool does not clear up within 48 hours, then add another dose of clarifier.
