Hey, Michael,

Actually, I may be all screwed up on that CYA dose. I looked at the chart for CYA dosage on that website I like and it calls for 1.25 lbs to bring 12,000 gal up to 40. It didn't seem like enough to me so I just rechecked and that's what it says. I know your Calc calls for 3 lbs. I've only added CYA twice to my pool ( used the dose off the side of the box ) but 3 lbs seems more reasonable than 1.25.

Here's the website: http://www.deh.enr.state.nc.us/ehs/chem.htm#ta

I'm gonna check some other numbers and try to sort this out.

Well, I just looked more carefully and the chart for CYA on the NC website is bogus. It looks like portions of the table are reversed where they actually call for LESS CYA to increase by 30 than to increase by 40!!. Obviously they transposed some numbers.

As always, trust Michael's calculator
