Hi--
I opened the pool just fine. Crystal clear, still had a bit of chlorine in from the winter. Six days ago my numbers were:
FC: 3.5
CC: 0
pH: 8.0
TA: 225
CH: 550
CYA: 60
I added some Muriatic Acid (first time tried this brand, Jasco Green Muriatic Acid from Lowes) to bring the pH down. I also added about 3lbs of CYA in a nylon in the skimmers. Then we had some family emergencies and I was away from home for a few days and yesterday the pool was cloudy. I did a few tests and the results were
FC: 0
pH: 7.1
CYA: 0
I know the only way to decrease CYA is splash out or diluting. We have not swam and there was about 3" of rain (but we have an automatic cover so the pool probably didn't get much water in it). Why would CYA be reading 0? I did the test three times all with the same result. Could it be that within 5 days my testing chemicals stopped working? I bought the test kit (Taylor) last year so all chemicals are about a year old, but they seemed to work fine when I got my numbers 6 days ago.
