Hey guys, I just moved into my first house and have started taking care of the existing pool (AGP, oval, ~10000 gals). I've been following all of your advise on this forum, VERY helpful, but had a quick question:
After testing the CYA with my TF100, it looked to be roughly 0 (very clear even when the cylindar was full). I added enough CYA in a sock suspended in front of a return to bring it up 20. From other posts in the forum, it seems like it takes ppl a long time to dissolve the CYA, but mine was completely dissolved in about 3 hours (I squeezed the sock a couple times).
Just wondering, is that is odd?
