I know what the formulas are. I used that one time to find my gallons. But it seems everytime I add what the pool calculator is, I always overshoot. Usually has to do with chlorine and I use 6% cholorox, unless it is actually stronger. So today I put in 1.5 to 6 and it say to add 206 ounces of 6%. So I did that, but instead of going to 6, I got to 12. So when I adjust the gallons of water I have to go from 22000 all the way down to 9500 to get the now and goal to come out the same. So is there any real way to figure out how many gallons my pool is. I know 9500 is not even close.

Thanks.
