No SWG. I just add 12.5% liquid chlorine as needed.

No, my CA was 60 during my last test and I only have to add water about once per week. So I should let my pH stay higher than 7.5? I've tried to keep it around the middle of the suggested target levels.

I have a 31500 gallon vinyl liner pool and it seems as if I have to constantly add acid daily to keep my pH at around 7.5. My TA has been running at between 80 and 90. Here are my test results from this evening: FC 5.0 CC 0.5 pH 7.8 TA 80 CYA 35 Is 80 an acceptable TA for my pool or should I...

So, I need to SLAM my pool but the weather forecast says thunderstorms every day/night this week. Am I correct in assuming that I will never meet the SLAM requirements with nightly thunderstorms?

So the mustard algae article in pool school says to SLAM normally and then bump up to mustard algae levels for 24 hours. So I would shock at normal levels (about 20 something ppm FC level) and then bump up to mustard algae levels (about 30 something ppm FC levels for 24 hours? Would just...

Sounds like it's not that uncommon to have a situation like mine (or ours Verndoggy). I guess the next question would be whether to use a polyquat algaecide after I get rid of the mustard algae. Any thoughts?

Yes, unfortunately it is starting to appear on the wall as well :(

Is it possible to get mustard algae and have your pool look crystal clear and pool chemistry stable? I have a 31,500 gallon pool and my chemistry readings are consistently as follows: pH 7.6 FC 4.5 CC 0 TA 80 CYA 55 CH 60 Every night I test and add 12% liquid chlorine to get my FC up to 6...
