Opened the pool early, didn't keep up with it very well, ran into some problems, and we've been shocking to clear that. However, pH has crept up during this process. So, added the muriatic acid to lower pH tonight, 15 minutes ago. How soon can I add bleach to bring back up to shock level? Also need to add CYA to get that level up---when can I add that with these other things going on?
