For starters, I am a new pool owner and the last owner left no instruction manual on the pool. I measured the pool and it's about 30ft long, 16 ft wide and 5.5 ft deep at its deepest.
We acid washed our pool so the water is new, about 3 weeks ago. However, we have been having trouble keeping the chemistry where it should be.
I had my water test done (a second time) with these results:
This was my pool's chemistry AFTER I had shocked it (causing the previous CYA 0 to jump to a 'high' reading of about 1) and put acid in it, a week ago.
Per pool store instructions, I just finished putting 35 ounces (16oz, wait 4 hours, etc...) then I shocked the pool and put conditioner in it and accidentally put phosphates in it a few hours after the conditioner (the verbal instructions just said to wait a little bit but when I read them (unfortunately after putting in phosphates) it said to wait 72 hours.
Anyway....now my FAC is on the high end of the reading (as to be expected) but the pH which was 7.5 four hours ago is back up to 8.0....what is going on with my pool...why is the pH rising so quickly?
Oh and I am located in Las Vegas, NV....right now the days are getting up to mid 80s but the nights cool down. Not sure if that makes a difference!
I think the water is pretty hard.
Any advise would be extremely appreciated!
