Now the water smells, and I have no chlorine, (strip test). I have read the FAQ's and am now more confused than ever...and this is my 4 yr. with a pool. I have a Jandy cl580 four cartridge filter, a Jandy hhp 1.0 pump, and it is about 26,000 gallons. I guess the first thing I should do is go get a "drops" test kit? ty for any help....
