The saga continues.

Chlorine only dropped from 38 yesterday morning to 35 by 2PM. pH measured about 7.6-7.7 w/sodium thiosulfate drops first. Added 91 oz (1/2 jug) bleach to raise chlorine to about 37.5.

By 6:30 last night, pool continuing to look clearer in the shallow end, still hazy with greenish/yellowish tinge in the deep. Had high winds all day so a lot of debris came in - just what I needed . At 6:30, chlorine was 32 and CC less than .5. Added 2 jugs (364 oz) of bleach to raise CL level by 10 to about 42 for the overnight.

This AM, pool 99% clear in the shallowest sections and clear on edges of the deep. Sun came on the pool and the middle sections and deep end still a bit hazy with that light greenish/yellow cast. FC was 43.5, CC less than .5 and my pH w/4 drops sodium thiosulfate, was over 8. First time I was actually seeing a purplish color in the tube. TA fell and is now at 40.

Added about half gallon of muriatic acid. Will let circulate for awhile and then add 2# baking soda. Won't put me where I want to be, but I can't help but think that my pool can't take being out of balance with super high chlorine, extra low TA and high pH for that much longer. This is such a different situation that what I had all summer.

As long as I'm seeing that light greenish/yellowish cast, I still need to keep up my CL levels, right? It's just hard to believe that anything could be growing in there at those levels.

Does anyone know if an algaecide is of any use as a preventive measure against this stuff?
