I would close all skimmers and only use main drain...this way if water levels drop, you want be pulling in air into your pump.
When I go on vacation the day before I leave I drop off a case of beer and LC jugs labeled “Monday/Thursday”, or whatever days depending on the strength of LC I have at the time to the retired guy that lives next door. On the designated days, he grabs a gallon of LC, dumps it in the pool, empties my skimmer basket, and sits on one of my lounge chairs drinking beer and reading a book because “he needs to make sure the chlorine mixes in” - that’s what he told me he tells his wife![]()
is chlorine tabs and floater a good idea?
how many 3" tablets to add? how much does it increase CYA by? should i still bring pool up to shock level right before I leave?
As you have the SWCG I would say just using some tablets to supplement should be fine.
Is someone going to add water if needed? At elevated temperatures you will get more evaporation.
