OK, we bought this house with the pool 4 years ago. Lived here my entire life suffering through summers. I thought I did the right thing by hiring a pool guy to come and teach me how to maintain it. Probably not a good idea, at least not that guy. And I'll admit, I haven't been the best about maintaining the chemistry. I had been pretty much exclusively using the pucks. The first time I checked the CYA using the Leslie's pool kit, it was off the charts (over 300+).
So, I'm turning over a new leaf. My TF-100 (and magnetic stirrer) arrived this week. The pool is on a SLOW drain (thanks to the Harbor Freight 1/6 HP submersible pump). I have a calcium line around the pool (rolled edge, no tile) and think I'll have them come sand blast it this week. I spent 15 minutes with lime-away and then muriatic acid/water solution and a wire brush and there is no significant difference on a 2-foot section.
Here's my question:
The calcium line has been sand blasted before (4 years ago). The concrete around the pebbles in this area looks pretty deep. Is it OK to sand blast it again? We'll probably do a full remodel in the next couple of years and get rid of the rolled edge and put in tile, so this needs to last a couple more years.
Any other suggestions before I start adding water back this week?
Thanks a bunch for your help!
