cya & chlorine levels

[Themadczar]

I love math and knowing how to calculate everything, but I find it much easier to go to poolcalculator.com and use the tools there... Especially the last one on the page which tells you the effect of adding X amount of chemical Y to your pool (just make sure to input your pool size in gallons at the top).

Another calculator that many of us like better can be found at the following link. I know that a lot of people do use the calculator that Themadczar mentioned above but it sometimes encourages people to put in a lot of a chemical to try and get to the target in one large dose rather than sneaking up on the target like we prefer.
