Here are my first set of numbers:
TA: 250 (seems very high?)
CH: 120 (turned a pink/blue, not a deep red, should I have kept adding drops?
CYA: 30 (just added more 3 days ago to bring it back to 30, already dissolved in sock in filters)
Should I be working on lowering the TA first or the PH?
Wondering about the CH test: is pink the red they refer to or should I have kept adding drops to get a deep red?
