Hello - I am looking for some advice. 10,000 gallon vinyl liner pool with DE filter. Readings over past four days below.
Pool is crystal clear. The only oddity is yellow staining on my steps - which I also had to deal with last year. I did not test for metals this year. Last year every test came back with no metal readings. However citric acid clears them right up - I just haven't wanted to lower the chlorine yet to clear them.
My question -- why the spike in CC? and what should I do about it?
I'm slamming each day as per quantities in the app.
Also working on lowering TA by lowering PH and aeration.
