I just bought a house with a pool (first time owner) last month and have now been reading the forum for a couple weeks (great place you have here btw). Just got my test kit today and did my first test. Took awhile since I read and reread everything, but I think I got it right, although the CH was really high... I was about to give up on the test and start over, but it finally turned blue. Here are my numbers:
CH: 710 (might have mis-counted a drop or two, but it's close)
The pool looks great, perfectly clear. Currently I have an inline chlorinator running with the trichlor pucks, but want to take it offline... Just need to get to the store to buy bleach.
Anyway, the CH and CYA seem to be the only items that are pretty far out of range. What should I attack first?
