Algae Problems
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:
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 SUN Tru-Blue® Super Concentrated 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:
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 SUN Tru-Blue® Super Concentrated 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.
PROBLEM: Yellow-Mustard algae is yellowish-green to brown in color; appears light and buoyant; powder-like appearance (almost like pollen). Appears on walls and in shaded areas of pool; can grow very quickly. Can be resistant to regular algae treatments.
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.
Choose the following algaecide: SUN Algi-Crush™
Be sure to brush with a brush compatible with your surface. Run the filter for 24-48 hours following treatment or until the water clears. Repeat treatment as necessary. Add SUN Tru-Blue® Super Concentrated 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 is maintained between 1-3 ppm.
PROBLEM: Pink slime is reddish or pinkish color in appearance, slippery feel and usually visible at waterline or around lights, ladders and other fixtures.
SOLUTION: Adjust pH to 7.2- 7.6 and be sure the Free Chlorine residual is 1-3 ppm. Check around lights, ladders, skimmers, etc., and brush all visible growth using a surface-compatible brush. Shock the pool using SUN-Burn® Extra, SUN-Burn® 35. Apply product per label directions. Reapply product until a Free Chlorine residual of 8 ppm is achieved. Hold a Free Chlorine residual @ 8 ppm for 8 to 10 hours after product application. Run filter continuously during process and for 24 hours after last product addition or until water clears. Add SUN Tru-Blue® Super Concentrated Water Clarifier to help clear the water. Thereafter, make sure to maintain the pH at 7.2 — 7.6 and that the Free Chlorine residual is maintained between 1-3 ppm.
PROBLEM: Water mold is colorless to white in appearance.
SOLUTION: Adjust pH to 7.2- 7.6. Check around lights, ladders, skimmers, etc., and brush all visible growth using a surface-compatible brush. Shock the pool using SUN-Burn® Extra, SUN-Burn® 35. Apply product per label directions. Reapply product until a Free Chlorine residual of 8 ppm is achieved. Apply product per label directions. Hold a Free Chlorine residual @ 8 ppm for 8 to 10 hours after product application. Run filter continuously during process and for 24 hours after last product addition or until water clears. Add SUN Tru–Blue® Super Concentrated Water Clarifier to help clear the water. Thereafter, make sure to maintain the pH at 7.2 — 7.6 and that the Free Chlorine residual is maintained between 1-3 ppm.
