    Pool calculator

    How do I make the water in my pool match up to the pool calculator? Meaning I should have a 10500 gal pool. but when I add the bleach it never goes to were I was trying to get it. Let's say I want to go from 4fc to 7 fc. I end up more like 11 every time. Right now I play bleach dice. See what calculator says than go under. If is says to add 96 oz I may add 50oz. Sometime I'm right sometimes I'm wrong. It is getting costly to keep testing the water. I will prob have to order more reagents again soon. This will be my third time ordering if I can't get this under control.

    Correcly identify the size of your pool first. You sig says 15' x 30' by 4' deep. Is that absolutely correct? Is the water 4 feet deep? Do you have rounded corners?

    How long are the straight sides before it begins to curve? Got a pic? Does the manufacturer state the gallonage?

    What's your CYA? Do you have the correct bleach %?

    Some dollar store bleaches aren't 6%. That may be part of the problem.

    Re: Pool calculator

    It is rare for them to be higher, lower is fairly common. I've heard of 6% being 8%, but never higher than that and not at all common.
