Finally had a few minutes to do a full test (TF-100) and was interested in some advice as I am a little unclear as to how I should prioritize. Here are the results:
TA: 80-90 (turned clear on drop 8, red on drop 9)
CYA: less than 20 (not unexpected, I figured I was at about 16)
My chlorine consumption has not been too bad, but I would like to get CYA up to 30, which means I need to add another two pounds. My pH is already low and I know it will drop further when I add mroe CYA, but I'm concenred about adding washing soda since this will raise my TA. I tried aerating for 12 hours the other day and saw no pH change (although I was sucessful in dropping my TA from 100). What would you recommend I do in this situation? Raise pH first just enough so adding the 2 pounds of CYA will get it back into aeration range so I can get my TA back down? Am I getting too hung up on the TA number and should I just get my pH where it needs to be?
Thanks for your help!
