This is Earl from Baton Rouge, LA. I recently bought a new home with a pool (see signature) and began to geek out on pool chemistry at TFP.com. I also need to give a shout out to Gilbee for helping me out via text messages so far. Long story short; The previous owner used dichlor pucks, I drained and replaced to reduce CYA from ~200 ppm to 45 ppm. I fed a little 10% liquid chlorine into the pool while I did this to keep if from looking like a hand grenade on bourbon street (green drink). My current results are as follows:
FC = 1.2 ppm
CC = 0.2 ppm
Ph = 8 (Went up from 7 during drain/replace)
TA = 150 (Went up with D/R also)
CH = 140 ppm (went down from 350 during D/R - We have soft water and I used a garden hose)
CYA = 45
I added the appropriate amount of Muriatic Acid a few hours ago to get my Ph in line before I start slamming. Pool Math says I need to achieve and maintain a TC of 18 PPM. I'll start this evening if a Ph test give me my goal of 7.2. I'll try to keep a photo log for y'all. I'll take care of the CH after the SLAM. If there's something I'm missing, please let me know. Pic #1 is included.
