Super high combined chlorine

[themaccs]

Well, i am still fighting, but perhaps not quite so hard. FC dropped from 15 last night to 10.5 this morning. CC was at 1.0 last night, up to about 1.5 this morning. I added 1 1/2 of the large (182 oz) jugs of bleach (so about 275 oz). Rest of my numbers look like this: pH - 7.2, TA - 150, CH - 200, CYA - about 45. I plan to come home mid-day to check on it.

Sounds like you're almost there. You'll know for sure when the Cl stops dropping overnight, when tested in the evening and again in the morning before the sun hits the pool. Just a note--I'm one of those that keeps my CYA intentionally 80-90 because I live in Louisiana with my pool in full sun all day. If I keep my CYA below 60, I lose almost twice as much chlorine during the day as I do with my CYA at 80. It's an unusual case, I know, but I'm just saying it happens.........

Mid-day not too bad - FC - 11, CC - just over 0.5 (1 drop almost cleared it). So another jug and 1/2 of bleach (about 270 oz). Seems like i haven't really lost much more FC between 6:30 am and now (1:10 pm) as I did between 11:00 pm and 6:30 am this morning - almost the same number of hours, but a LOT of HOT Sunshine today.
