    Is my chorine feeder valve plumbed backwards ?

    Is there chart or formula that shows relationship between CYA and %FC loss per day ?

    I'm looking for a chart that would show the CYA vs %FC loss per day, given say water at 85 degrees, and in Texas with full sun on pool. The reason I'm asking is I want to confirm my CYA testing is ballpark and I'm getting the expected loss.

    What would happen with very low cya and only adding bleach in evening ?

    It is well known that chlorine is much more effective when cya is low. What would happen say if cya were 0 and fc raised to say 1.0 each evening using bleach after sun went down ? The lack of cya would make the chlorine very effective overnight, during day sun would rapidly drop fc. would...

    Why is ideal range on test strips so low for FC

    Thanks Jim/Dave, I think then people get in trouble with algae that use pucks and the strips. Everything looks okay to them based in strip ideal level, but the fc needs to be much higher as they build cya. Im using bleach. For me the big problem with pucks is need to drain on occasion. The...

    Am a new member and have some questions.

    Thanks for info. I'm going to try switching to using bleach. The builder left me bucket of trichloro-s-triazinetrione tablets. My cya level is 39 and when it drops to 30 ( due to backwashing ) I will start using that bucket again to use them up.
