I bought a house in March and have been using information on this site to help me get the pool balanced. I have a teenage son whose friends use the pool too. The former owners were elderly and had a pool service come by weekly. It's a 20 year old large pool (40,000 gallons) with a diving board. The plaster has some stains that I am starting to troubleshot and I have 5 lbs of AA on hand. It could be the original plaster (not certain though). Also some of the aggregate concrete decking is cracked by the diving board (unknown cause). Current tft-100 results are:
FC - 7
CC - 0
TC - 7
PH - 7.6
CH - 225
TA - 90
CYA - ~40
Borates - 50
I'm a widow and do the testing/chemicals myself. I'm very grateful for this site. I feel it's gotten me off to a good start! I did grow up with a pool in Illinois and remember my dad using a test kit, sanitizing primarily with liquid chlorine and don't recall any issues with the pool - ever.
