What about dilution? By adding water almost daily, don't I dilute the CYA and the salt?

[chem geek]

Only if water is physically removed before you add fresh water. Otherwise, with evaporation only water gets removed and not the water's contents (CYA, salt, etc.) that simply get more concentrated. So when you add more water it does get diluted, but back to where it started.

Imaging half of the water evaporating. In that case, a CYA of 50 ppm would become 100 ppm because there is the same amount of CYA but now in half as much water (so the concentration gets doubled). When you add fresh water, you dilute this back to 50 ppm.

Okay, I'll quit trying to figure it out...it is what it is!
Thanks!!

Okay, finally did the bucket test...I concede that I seem to have a leak. as I understand it, the next thing I do is plug up all lines going in and out of the pool, but I don't know how to do that. Sorry to be dense.
Thanks.

Probably at this point, what you need to do is just keep using your pool, and keep your eyes open for a leak. Save the pipe testing till your water is cooler and will 'keep' better, with the pump turned off!

I've been looking at youtube videos and may try to see if I can find leaks in my liner...am hoping that's the problem! I did learn how to plug all the lines The more posts I read on here, the more problems I discover with my pool. Thank goodness for all the help!
Thanks.
