Thanks for the quick replies. The water looks awesome, I had another much smaller pool and it was never this crystal. It has grey plaster and blue 3m quartz and it is very "sparkily" . As far as the fire hose, I had to give the city a 750 dollar deposit and they gave me a meter to hook to the hydrant. They then subtract the water cost from the deposit + 100 dollars. It was worth it to get 45000 gallons in the pool in 2 hours. Our only concern right now is the white deposits on the tile, we hope they are from residual plaster. Thanks again for the advice, how often should I run the full water test?
