Hello,
I have a 25,000 gallon/in ground vinyl/sand filter. The pool is older (25 years or so) and we bought the house 2 years ago, this is our third summer with it. The filter just wasn't working well the first 2 years so I changed the sand out this year and its working well.
Now I have a totally new problem that never happened before. The pool has a green tint though it's perfectly clear, not foggy at all, just a light green tint to it. The deep end show's it the most. This ONLY happens right after rain (even a small amt) or I top off from my well, again even a small amt will cause the deep end to go green. It takes 2-3 day's to return to clear but it does return to crystal clear on its own every time. I just re-tested my well water for copper and iron and it has none. Below are my pool water test results from this morning. With my limited knowledge I can't see anything here that would explain this?
Temp - 74
FC - 4ppm
TAC - 4
CH - 110
CYA - 35
TA - 7.0
Base - 5
Copper - 0
Iron - 0
TDS - 500
Thank you all in advance for your time and any assistance!
