Hi All!
Well, my pool looks great, but the scaling issue is getting worse. My pH is usually 7.7-7.8 so I've been adding acid every week, but the scaling is just getting worse and worse. I haven't noticed any changes in the plaster, just more flakes, and my robot is saturated with it when I clean it (see pic; this is about 5 days's worth of 1.5 hrs/day). I know I need to drain the pool some and replace with fresh water, but will that really help? If the pool level drops about 6-8 inches a week and I refill it, isn't that kind of the same as draining and adding new water? I need to get a sump pump. I don't know how to use the filter to drain.
Last week I had the water tested at Leslie's to compare numbers. I had FC of 2.0 and they got 4.0, telling me it was too high. I asked how they calculated the FC and they couldn't explain it. I know this forum says to not trust their numbers, but I got worried because I already added bleach to the water to bring up the FC since I was expecting bathers that day, and they were telling me I needed to lower it. At the bottom of Pool Math in blue for "Suggested FC Levels" it says "SWG: 4, Normal: 7 to 12." Does that mean my FC should be between 7 and 12 ppm? Seem high. Leslie's also said my salt was at 3850, and my wall remote said it was at 3000! Ugh! What's the best way to measure salinity? I don't mind spending a little money.
Okay one last thing. Sorry, I don't get much time to post on here so trying to get all questions out. I noticed the one of the return jets, the strongest one nearest the pump, now has a pretty consistent stream of bubbles. I read somewhere on this site what that meant, but I can't remember where I saw it. What does that mean? Is it serious?
This morning's tests: FC = 3.2, CC = 0, pH = 7.7, TA = 110
Thanks for your time!
