Do you do anything additional or special after swimmers, particularly regarding chlorine if levels seem ok? (This may be a dumb question but searched everywhere for answer and couldn't find it.). Tested FC this morning and was 4. Then tested about 2 hours after swimmers and it was 3, where it normally is at that time every day. Therefore, seems we hardly lost any due to swimmers. Had hubby raise to 5 but wondering if we should add more since we had swimmers. We use strictly liquid chlorine, no tabs.
FC 3 last time checked but in process of raising to 5
