We had our pool replastered 2 years ago and we have been getting a lot of white residue in the water. I finally got around to testing my CH and it is quite high. From what I am reading, the only way to lower is to replace water? Here are all my numbers:
FC 8
PH 8
TA 130
CH 870
CYA 60
Salt 4800
CSI 0.84
My tap water CH is 170.
What do you advise?
Another thing we noticed last year, about a year after the replastering, were several stains that look like smears. I tried SLAMing last summer and it didn’t affect them. I tried pumice stone, and brushing, and that doesn’t take them off either. When they replastered the pool, the workers spilled a bunch of plaster in our yard. We suspect after they scooped it up, they reused some of it. I don’t know if that would cause these stains or what. Sigh. Not sure there’s anything we can do so long after the job was done but the stains did not manifest until much later. Any thoughts on this?
