High CYA may be the root of my problems CYA at 99--
Jandy/zodiac SWA quit this winter, just replaced with new 3 port cell, doesn't seem to be producing any free chlorine.. but all tests show working proper... HELP
Pool store (Leslie's) test:
CH: 550 (high)
Free Chlorine goes high after adding Clorox Dichlo, and goes to zero quickly
Leslie's Pool sold me new expensive "Zodiac Perfect weekly" for phosphates
Pool goes green overnight with some black algae on rock scapes
I live in SoCal, very expensive to drain pool.. but chems are expensive too!
Question-- is CYA my problem? pool store didn't say anything about that!! I read the sticky, ready to attack the pool... do i need real chlorine vs. Dichlo packs? am I wasting time with CYA.. is there anything I can do about that? do i need black algae killer.. or just chlorine? ... is my SWG not producing because of CYA?
