good to know. maybe I’ll do a couple mid day additions. I should have trusted the text and done that from the start knowing what I know nowSLAM levels of chlorine will lose a lot more FC to the sun than when it's down in maintenance levels. You lose more FC to the sun the higher concentration of FC is in the pool. That's why the maintain part of "SLAM" is important - gotta keep replacing what the sun eats up to keep that FC level up where it's keeping any algae dead.
