This is my 3rd season on this site. I am a BBB success story. I came into this site 2 years ago with major chlorine demand issues which was basically caused by pool store chemicals getting my CYA to well over 100. I first stopped going to the pool store and adopted the BBB method. I was able to bring down my CYA slowly by lowering pool level way down at close and filling with hose water when needed.
Last season I performed the famed SLAM process and it worked like a charm(be patient people and listen to the expert contributors on this site). Once I finally got my chlorine to hold I was adding about 1 gallon a day and my PH was constantly rising to >8. Then I closed.
Now I just opened and was able to get my pool clear within 48 hours(personal record). I took my measurements yesterday with my TF-100 and the numbers are pretty much what I expected(good thing). Now I want to get my chemistry right but I am unsure which of the 3 trouble spots I should fix first. Here are my numbers:
PH 8.2 !!!
FC: 8.0
CC: 0.5
TA: 30 !!!
CYA: 0 !!!
I think I need to add Muriatic acid to bring PH down but I thought that would drive the TA even lower? I suspect the real issue is my, pretty much non -existent, CYA. I fought so hard to get it down it is hard to do anything to bring it up, but I recognize I need to add some CYA to stabilize the pool. I am just not sure which of these three to tackle first? Suggestions?
