Though I've done a full analysis of my pool chemistry and in the process of adjusting my pH, I was wondering if I can still test my pool for pH, CC, CYA, FC, TA and CH after adding PolyQuat. Just curious.
Adding Polyquat will consume FC. If you intend to close the pool then use the recommended ratios that were discussed in Let CL level drop to half normal level??? with you. If you add Cl you can reduce the effectiveness of the PQ.
