I tried to search but didn't find anything. I help out my next door neighbor. They are grandparents and have the pool for the grandkids. He has a 30k inground pool with VL and DE filter.
The thing is when I test for chlorine, the pink doesn't go away when I add R-0871. I went up to 40 drops and it was still pink. He hasn't added any bleach in two days and only has the sticks in the skimmer.
His CYA is at 100.
PH is at 7.6
I'm using a Taylor K-2006 test kit.
Also what is odd is when I test for TA the color goes from green to blue and then turns gold at 120 drops of R-009. It doesn't go clear.
This is baffling me. I do notice that there seems to be a yellow algae on the bottom and steps of the pool. Not a lot but you can see it. I'm guessing mustard algae? Could it be so contaminated with this algae that it is messing with the tests?
Any help would be appreciated. They are both in their 80's and I try to help out as much as I can. They are awesome neighbors.
