Been testing with a good kit for 7 days now. Everything has been pretty stable. Water looks great. The TA and CH have been dropping, though, and now I think I need to boost them after looking at the Pool Calculator. I have a 5lb container of Alkalinity Balance Control A.B.C. I bought before finding this site. It doesn't say what's in it. Is it just baking soda, as Pool School suggests it might be? Any idea if it's worth using? Here are my current numbers:
TA started last week at 150. CH started at 100. PH hasn't budged since day 2, when it was 7.2. Been keeping FC between 4 and 8 as suggested here. CC has bounced from 0 to .5 to 1 and back.
Also, what is the best way to get the CH up? Pool Calc says calcium chloride or calcium chloride dihydrate. I haven't seen these is the pool store or the Home Depot. Where can I find it? Are there any other names I should look for?
