Hey all. Just drained recently and had a company add some cya after they got the pump up and running. Currently PH and alkynity are good but my chlorine, cya, and calcium are all pretty low. Does it matter in which order I balance these out? Thank you
Calcium, CYA, and Chlorine are all low. Which order to balance

Chlorine is always first, as long as you are testing with your own reliable kit and not depending on questionable pool store testing. Here’s a link for details on why:

Welcome to TFP.
Chlorine always first if it is low.
Be aware adding calcium has found to cause FC to drop to 0. Watch your FC level after adding calcium and raise it back up if it drops.
Stabilizer/CYA will lower pH a bit but your TA should raise your pH naturally.

What test kit are you using?
Post a full set of current test results.
FC
CC
pH
TA
CH
CYA
Salt (if you have a SWG)
Water temperature
Post your tap water pH, TA and CH as well
Likely your tap water CH Is 175-250. With evaporation as our temps rise, the CH will increase as well.
