    Does algaecide alter the Chlorine Levels?

    I searched but I could not find this answer.

    Does algaecide alter the Chlorine Levels?

    I am fighting an algae problem. I shocked the **** out of the pool and added algaecide. I also have Chlorine tabs in the floater.

    I tested the water 24hr later and it shows little Chlorine. Does the weather have anything to do with it? It is in the high 70’s and cloudy if that helps.

    Your chlorine most likely was consumed by the algae. Read "ABC's of Pool water chemistry" up in Pool School.

    Additionally, don't purchase any more algaecide. It has little affect on killing algae......only at prevention. The Tabs are not helping you much, either. You need to shock the pool (read how in Pool School) with liquid chlorine, Cal Hypo, or di-chlor.

    I would not go further in the shock process until I had a complete set of test results....preferably from your own testing but a pool store test can SOMETIMES be useful. That'll help us help you to clear the pool.
