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.

Hi PF team,
My water is looking great. I probably have a leak somewhere but can't find it in the liner. I test FC and pH daily and often have to add acid to keep pH right.
So, here's my new problem. My pump is on a timer. I've noticed a few times recently that pump is turning itself off before end time on the timer. Sounds like the pump is overheating, maybe? Other thoughts? Is it time to call my pool guy?
Thanks.

What do you mean, "turning itself off"? Is the breaker tripping? Is the pump turning off, and then after 10 - 15 minutes back on?

The latter behavior would be typical of a pump turning off on an overheat safety.

[Kateyru]

The pump turns off before end time per the timer. It has not turned back on but I don't know how long it's been off. I've just noticed that it is off "early" so to speak. It is not tripping the breaker, and I have been able to turn it back on as soon as I've realized it's off. Hope that makes sense.

[PoolDoc]

I can't tell anything from that description. Can you turn the timer off, and leave the pump running? If there's a problem with the pump, it will shut itself off at some point. But, if the problem is with the timer, the pump will run uninterrupted.
