Just opened...using TFP Test kit...it appears CYA may be zero (black spot in tube never grays out even when tube is full!). Can that happen in one winter? If so, assume this is first thing to tackle or should I start putting bleach in pool immediately (green), OR deal with high ph first?
Current NO CHLORINE; no apparent CYA, PH 8.2+ and TA 7
When should I SLAM...now or later?
