Just bought a house with ~18k gal pool and spa. Water looks crystal clear but when I tested it FC, TA, and CYA were super high. Didn’t test CH. These were my results with TF-100.
FC: 17
CC: 0
PH: 7.5
TA: 17
CYA: Wayyyyyy over 100
I spoke to the service that had been maintaining it and he told me alkalinity, cya (140), and total dissolved solids were all high, but told me I’m doing the chlorine test wrong and they keep it at 3-5 ppm. I did the color match test and chlorine was bright orange, and then FAS-DPD and used 44 drops last night and 34 this afternoon.
First question, am I doing the chlorine test wrong? I read all the instructions closely but feel like I must be doing something dumb to be so off. Second question, drain the whole pool or just 2/3rd as the service recommended? Any tips for starting from scratch with new water? I read most of pool school but my head is spinning.
Apparently the pool was in bad shape all winter and owner refused to drain, and now they’re using a lot of chemicals just to make it look clear. Appreciate any help!
