Algae Problems in your Pool?
By Costa Rica Pools and Construction
Algae are single-celled plants that live in water. Following are conditions that may contribute to algae growth: High pH (over 7.6), low or no Free Chlorine residual, poor water circulation or short filter.
PROBLEM: Green algae is the most common type of algae. Usually floats freely in water but can grow on the surface as well. It causes “pea soup” green water.
SOLUTION: Adjust the pH of the water to 7.2 to 7.6 and be sure the Free Chlorine residual is 1-3 ppm. Algae treatments will be much less effective if the pool cannot maintain a chlorine residual. Each algaecide has specific application information on the label. Read and follow label directions.
Use the following algaecides:
- Tri- Coppercide from Costa Rica Pools
Success will be improved with proper brushing of the pool. Run the filter for 24-48 hours following treatment or until the water clears. Repeat treatment as necessary. Add Sparkling Blue water clarifier to help clear the water of dead algae and debris. Thereafter, make sure that the pH is 7.2 — 7.6 and that the Free Chlorine residual between 1-3 ppm is maintained.
PROBLEM: Black algae has a dark black color and appears as sporadically scattered black splotches. Sometimes appears as tar-like deposits on bottom. Can be difficult to remove with scraping; attaches itself to pool walls (primarily plaster) and sends roots deep into the finish.
SOLUTION: Adjust the pH of the water to 7.2 to 7.6 and be sure the Free Chlorine residual is 1-3 ppm. Algae treatments will be much less effective if the pool cannot maintain a chlorine residual. Each algaecide has specific application information on the label. Read and follow label directions.
Use the following algaecides:
- Tri- Coppercide from Costa Rica Pools
Be sure to brush with a brush compatible with your surface. Use a stainless steel brush for plaster (gunite) pools. Run the filter for 24-48 hours following treatment or until the water clears. Repeat treatment as necessary. Add Sparkling Blue water clarifier to help clear the water of dead algae and debris. Thereafter, make sure that the pH is 7.2 — 7.6 and that a Free Chlorine residual is maintained between 1-3 ppm.
The best way to prevent algae is to keep your water balanced and have Free Chlorine maintained at 1-3ppm and use CRP ALGAECIDE as a part of your weekly chemicals to prevent algae from forming. There are many factors that introduce algae into your pool like heavy rain, using the same swim suit that you used in the river without washing it, letting chlorine go below 1 ppm and not running your filter long enough.
