Algae Prevention & Control

ANALYSIS: Algae growth is usually caused by one of the following conditions:

Inadequate free available chlorine levels. Free available chlorine levels can be depleted quickly by heavy rains, high bather loads or poor maintenance procedures. During such conditions, check free available chlorine levels frequently and add an Aqua Chem sanitizer as needed, according to label instructions.
High pH. Alkaline water prevents chlorine from effectively killing algae. Aqua Chem pH Decreaser used as directed on the label will lower pH to the correct level of 7.2-7.6.
Dirty Pool Surfaces. Dirt and slime accumulation on pool surfaces provides the perfect location for algae problems to start. Weekly brushing and vacuuming eliminate this source of trouble.

SOLUTION: Aqua Chem Algaecide Plus^®

Check filtration and circulation systems for malfunctions.
Check the pH and adjust (if necessary) to 7.2 — 7.6.
Following label directions, add Aqua Chem Algaecide Plus (for all pool types).
Allow algaecide to work overnight. Then brush and vacuum pool surfaces. Backwash the filter to remove accumulations of dead algae and debris.
For major infestations, a second treatment may be needed.
Return to normal maintenance with Aqua Chem sanitizers, shock products and balancers.
As an algae preventative, add Aqua Chem Algaecide Plus or Algaecide Concentrate 60% per label directions as listed for preventative maintenance.
