first off, some test results for you all:
FC - 3.0ppm
CC - 0.0ppm
pH - 7.8 (added 1 gal acid)
TA - 180
CH - 150
CYA - <30 (probably closer to 15-20)
so I like running low CYA, it allows me to run low FC so I don't get any chlorine smell/taste while swimming, I'm raising it closer to 30 currently with trichlor tabs (4 8oz tabs raise it ~5ppm, I'm on my second batch of 4). calcium I'll handle as CYA gets closer to its level, I'll be using 50lbs of cal-hypo over the next 1 1/2 month for shock and maintenance chlorine, should raise my CH by 115ppm, but the stickler is I can't lower my TA by adding a chemical, and it doesn't want to drop for me. I've added 1-2 gallons of acid over the course of a week and still can't get it to drop. any suggestions, I know aeration, any suggestions for an aerator?
