Spending a frustrating night and came here for some advise.
First pool specs. I have a 27,000 gallon in ground pool. Hayward DE filter. Jandy Heater. Hayward Chlorinator Nature 2 mineral cartridge. PH 7.6.
In April when I opened the pool pool water was fairly clear but had a lot stuff on the bottom resembled dirt. Vacuumed it up appeared again the next day. Thinking it was algae. After getting a new pool vacuum (dolphin) I was able to keep the "dirt" in check better. After several back washings pool water was crystal clear but wasn't able to keep any level of chlorine. Noticed pucks weren't dissolving so go a new o ring in chlorinator and that is working.
Backwashed again and with a clean looking pool I started SLAM. CYA was 40 raised the Chlorine level to 16-18.
Checked in 90 minutes it was down to 12 CC was 1.0. Added more chlorine back to 16. An hour later was back down to 12 added more chlorine. TC 16 CC was 1.5. Went to bed. 7 hours later Chorine is 1.0 and CC is .5. Added more chlorine.
I need to backwash filter as the pressure went up from 18 - 25PSI. From all the dead algae I guess.
Added more chlorine. Pool is still crystal clear other then green deposits near the jets where return water is coming into the pool.
I've already gone through 12 gallons of chlorine.
Do I just continue like this?
