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.
- Vacuum up as much of the algae as you can see.
- 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.
- 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.
- 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%).
- 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.
- 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.
