According to the Pool Calc if you started at zero it takes 97 oz by volume to get to 70 ppm CYA.
TA=Total Alkalinitymimidjets said:Not sure what the TA is.
Aeration does raise ph...in fact it is one way to also indirectly lower TA since every time you lower ph with Muriatic acid (or dry acid), you lower TA a little.mimidjets said:Also I read somewhere that fountains and things like that can cause your ph to rise. My intake has a control on it where I can raise it up out of the top of the water or down into the water. It has a pretty strong movement coming in. Could that be a problem?
PH rises through swimming, splashing, SWG. It's normal for it to rise. When it does, add your acid.mimidjets said:Wow, I thought my 210 was high! I am glad to hear that! I won't worry so much about mine now! I don't mean to sound stupid or anything, but I just don't understand the pool calculator. I tried putting in my information, but it makes no sense to me. I have put muriatic acid in twice so far to lower my ph. Both times I put 20 oz. according to package directions. It stayed low the first few days, but came right back up. Do I need to put more, or just put it more often?
