Wow, that more more than 2¢... more like $20 worth. Thanks for the in depth answer. On start up I put in the 2 part A liquid/B powder to bring my bromine reserve up at initial fill. Ok to sum up the rest, sorry if I get things wrong, its been 6 months since I touched pool chemicals. I can shock with Bleach. Use borax to bring my Ph up when needed and dry acid to bring it down. where do I buy dry acid anyways, is it available at my local hardware store?? and how does baking soda fit into it? Yikes, this is what happens when you dont have your pool open all year around, you forget!

Now I just have to wait for some warm weather to drain my hot tub :-(
