I'm having trouble keeping the chlorine level up. Using liquid chlorine from Wal-mart but that's usually gone in a little over 24 hrs. I bought a chlorine floater today w/ 3" tablets.
1) Will the tablets break off in little pieces and damage my pool? & if the floater sits at the edge of the pool will it damage it?
2) Will the combined use of chlorine tabs and a gallon of liquid chlorine keep the chlorine level up in my pool?
3) Lady at the pool store said just to throw in granular chlorine. Won't this damage my pool? I know one time a relative threw in liquid chlorine and it made a light/thin spot on the bottom of the pool (which is why I had to throw out the pool last year after patching it).
4) How many tablets should I put in the floater at a time?
My pool is around 6400 gallons.
