Chemical Dosages

How much of these pool chemicals should I use in my pool?

These charts should give you a rough idea of how much of the various pool chemicals to buy and use. Our suggestions for a season's supply are based on past experience in a 90-day season, with average weather. Of course, your actual usage will depend on such variables as: type of filter, local weather, closeness to trees and plants, careful water testing, and luck. Always read directions carefully, and consult a pool professional if you have any questions.

NOTES:

1. Dosages of these stabilized, concentrated chlorines are based on a pool initially stabilized with Robelle Chlorine Stabilizer.

2. Only careful testing of your water can determine when and how much pH Rise or pH Lower to add. Follow directions on the container.

3. Algaecides, Clarifiers, and Mineral Removers are generally only required when you have specific problems with algae, iron, or cloudy water. Some pools may never require these chemicals, while others need regular applications.

4. Non-foaming Algaecide should not be used in gunite, fiberglass or concrete pools.

5. If you have stabilized your pool water with Robelle Chlorine Stabilizer, and if you always use a stabilized chlorine, usually you will not need to add more stabilizer. However, if you use unstabilized chlorine or if you backwash a lot of water out of your pool, or if you lose a lot of water through evaporation, you will probably need to add more stabilizer. Have your water tested by a professional before adding any more.
