The bromine level does hold without a drop during the day. the liner change won't happen until the fall so I'm stuck trying to get this thing going as is. I'm off from work tomorrow so that's when I'm doing the chlorine shock. the cover fell in over the winter leaving a bit of a swamp, it was clearing steadily until the pool store had me add phosphate remover, then it stopped clearing. is bleach from walmart sufficient to shock or should I get the more concentrated stuff from the pool store and how much?
(20,000 gallon IG) Thanks again, Paul
