Ok been learning and messing with water and testing all week. It's 82 out and would love to go swimming. I tested last night and all my fc was gone again but I also had no cay in there so it wasn't staying so I put my usual 4 cups in plus 3 extra thinking maybe today Fc level would be perfect. I also added instant conditioner to get that up. Well aparently too much bleach was added And the conditioner kept it from evaporating.
CA 35ish right in between 30 and 40.
No combined clorine
Or do I need to wait until fc burns off.
