First and foremost, so I don't get hollered at, test results:
FC - 3.0
CC - 0.0 (<.5 at least), FC was 3 at 9pm and again at 9am
pH - 7.4
CH - 40 (just added 10 lbs this morning)
TA - 180
The top step has missing plaster spots and I am wondering do I drain the pool down lower than the top step or use one of those underwater repair kits?
next, the staining. we had black algae last year when we left on vacation for a week and used cal-hypo (?) in the skimmer (it was the one that's made for in a skimmer), apparently bad circulation. I tried the metal brush with high chlorine and it really didn't do much to remove the staining, rubbing trichlor puck yields what you see, it removed the stain quite well but I'm worried I might be causing damage to the surface. don't mind the leaves, the polaris is cleaning the pool currently. the staining can also be seen in the first picture.
finally, I asked this question before but never found an answer. how well does the "acid washing" without actually draining work? I was told I could do a 50/50 water/acid and sprinkle with a gardening can down the sides and brush with a metal brush and its just as good as a full acid wash w/o draining, especially since we live in an area with a high water table (is that what its called?).
anyways, here's my pool and my neighbors pool. the kicker, nobody has lived in that house in 1 1/2 years, yet the yard has been mowed and the pool sparkling, both by a service. so who is paying for this and where are they?
