Good plan.Added another gallon of liquid Chlorine targeting 16ppm FC, also pulled the wet sock (with undissolved CYA crystal) out of skimmer. Will put it back once SLAM is completed.
We got you. You are on the right track. A SLAM is very doable at CYA of 50ppm.Need to buy more liquid chlorine tomorrow noon, then test CYA again to decide if FC needs to be further increased and maintained tomorrow afternoon. Will do OCLT tomorrow night, plan to do Saturday full day high FC level and OCLT, too.
