I did a test and found my ph at 7.2 and the TA is 100 with the cya at 30. Should I get the cya up first to 80 and then work on the ph or the other way around. It is going to be awhile before we can swim because the weather here in NW Wi. can't even get to 70 and I don't have the heater hooked up yet so I have time to get the levels perfected.
