All right, I will aim for 60-80 CYA - thank you, and I will try the borate for sure. I am trying to figure out the math using the bleach calculator, but I do not know how much 10.5 % sodium hypochlorite weighs per pound. It doesn't say on the bottle & I have gotten several very different numbers off of the internet.

Do you have that number so I can figure out how much to raise 1ppm. Thank you!
