we started up our pool back in September and thanks to all the help from this site, I thought I knew what to do to avoid any issues. I keep the PH under control with acid etc...
Well in January, we had a few small issues that I had to call my PB to come out and fix, one being the autofill float...it had broken. When fixing it, he told me he was re adjusting the water level because it was a little high. About 2 days after this, I notced the calcium stain all the way around the pool tile and gunite boulders that go into the water line. AHHHH!
I brushed the pool religiously, including the tile prior to this, so I was dissapointed to see these stains. So, I first tried a pumus stone...no help, then I tried 4 to 1 acid...no help...so I went 50/50 acid...still no help....so off to the pool store to find something that would get this crud off. I found scale away....guaranteed to work. Guess what, it doesn't, at least not for me.
So, I have read about glass beads and I really do not want to do that. Am I stuck with this stain? WHat can I do? I have this beautiful pool, but it is a little emabarrasing to have this stain only 9 months after filling it up.
This is a salt pool and my most recent test results are:
FC - 5.5
CC - 0
TC - 5.5
pH - 7.5
T/A - 90
CH - 280
CYA - 40
Pool Temp - 87
Any help or advice would be appreciated.
