Hi all, bought a foreclosed house a couple months ago, pool was pretty nasty, so it took quite a bit to get it usable. The service I worked with had me add 25lbs of baking soda, lots of chlorine, new filters, and 2 weeks of constant filtering. Wish I had the original tests but I've lost them (arg).
Water looks great now and we've used it quite a bit, but for the life of me, I can't get these black spots out of the plaster and more seem to appear each week. The pool and spa also have splotches which I assume is plaster wear?? For the black spots, I've been mainly scrubbing (hard as ****) with a wire pool brush. I tried a crappy pool stone, but that did nothing but disappear in 30 sec.
Recent test results (from pool service, using manual test with taylor kit):
- TDS: 410
Tot Chlorine: 8
Free Chlorine: 8
Total Hardness (?): 150
This is my first pool so everything is new to me. Appreciate any tips you can spare, thanks!
