Thanks Butterfly I think that's a good call. I took the full test to make sure I was still within tolerances of the other values but you have a great reco - I'll stick to FC and CC for now
Good news, my pool was extremely clear this morning and my levels were at
FC: 14
CC: 2.5
But, I think I added a bit more Chlorine than I needed to last night (it was the 0 FC, perhaps I was a bit trigger happy...) I was going to pick up some CYA today - is there a specific brand/location/etc I should be picking this up at? Is there any difference between a pool store and Sams club/Walmart/big box retailer? Brands or ingredients I should be avoiding? Also, how much CYA do you normally use - is this a consumable item (i.e. should I be buying in bulk or just enough to get the set levels?)
