Our pool is a bit over a year old and maintaining levels has been pretty easy so far. I use a stenner to dose chlorine and do everything else manually. Just recently I noticed a lot of staining, it really seemed to creep up on us. I posted a picture where you can see the clean and dirty spots. The streaks are from the infloor cleaner and the clean square shaped spots are probably where our robot cleaner was resting. I have a feeling the staining is a combination of our AZ dust storms and high CH. And I don't think I kept the PH as low as I should've, and to top it off probably didn't brush enough.
Any advice on what chemicals to add, or a recommendation to just drain and acid wash?
FC=1 (our stenner timer broke, so I'm bringing this up to about 5-6 right now)
TA=70 (this was always within range, but has just dropped recently)
CH=590 (our tap water registers as 20)
I've been trying to keep PH lower and brushing a lot. I do see some dirt coming up, but to be honest I can't tell if it's getting better or worse.
