I bought the Identifier kit from Jacks and clearly the #2 Stain solution is what I need. The stains in my pool I think are from a 10 year old failing heater. I was trying to keep it going for a couple years longer then I should have and assume the copper plumbing in it was disintegrating and caused the staining. A coffee filter bag of #2 stain solution placed in the middle of one of these stains made it disappear in seconds and my 3M blue quartz finish glowed. Really impressive. The other two stain solutions in the identifier kit did nothing.
I understand that I have to isolate the heater from this but my question is if I go ahead and spend like $500 for the stain solution, and it does release the stains from my plaster, where does it go? I have what I consider a construction grade 4 cartridge Hayward filter. I'm assuming the cartridges will get ruined. Or, am I suppose to dump the jacks in the pool then drain it?
I have a 27,000 gal in ground pool, gunite/3M quartz plaster finish. No metal steps or railing at all in the pool. The only think metal would be the 2 lights.
