Below are my previous numbers and required a partial drain and fill.
Before drain and fill
CYA 100+ Still don't reach first line on test
I guesstimate I changed about 75%, which I still feel guilty about being in drought town CA. So now I present my new numbers for your review.......
After drain and fill
FC 2.5 (floaters are out of the pool and I added 6% bleach! But I need to double for my CYA)
CYA 70 (looks like I had a ton of this stuff)
