New pool owner and I have adjusted all levels to within normal parameters with the exception of FC, which is reading very high at 15ppm. IS it OK to leave it at that and let it drift down normally? I have an inline chlorinator that I stock with the HTH 3" Tri-Chlor tabs and am also worried about my CYA levels creeping up, is there another alternative to the tabs that will not raise CYA? I have been toying with the adjustment level on the in line chlorinator, steadily decreasing it, now set on 3. Thanks for any suggestions.
24k gallons, 36*18 inground pool, plaster, DE filter, I'm in Boston and pool is in direct sunlight most of the day.
