Should i replace my salt cell or the whole system

Pool Doc,

Its been awhile since I have been on the forum but I thought it was not good to have your CYA so high (as 100+) as the only way to get rid of it is to drain the water from the pool and high levels of CYA force you to keep the FC very high. I always targeted a CYA of 40-60 so I could keep my FC at the 3-5 PPM level. Or am I remembering wrongly?

That's true, but if you maintain the ratio between chlorine and CYA, your chlorine consumption doesn't increase, as the levels increase.

What does happen is that you are able to 'store' more and more chlorine in the pool. When you get to CYA = 150, you can add chlorine just 1x per week!
