Should I raise my cya?

[amillionpets]

I just read through all of this because I was wanting to know the answer to the initial question as well. Maybe it was in the thread and I missed it? So, should I raise my CYA to keep the FC from dropping so quickly? It seems I am adding a lot more bleach this Summer than last. My CYA is 40. If I raise it to 60 will that help stabilize the FC level a little longer?

Why don't you try raising it to 50 first before deciding to go to 60. You can always add more CYA but can't remove it. You may find that 50 works better. If not, easy enough to add more.

The best info we have at the moment is that -- generally speaking -- if you run your chlorine at 10% of your CYA level, you will lose about the same chlorine, regardless of levels. Put another way: you'll lose about the same amount of chlorine daily if you maintain FC=3 if your CYA=30, as you will with FC=8 and CYA=80.

However, there is some unconfirmed information that suggests that you will lose less at very high FC/CYA levels (FC=15; CYA=150). But even if that info is correct, the improvement is not huge.

Ah! Thank you both very much! That is very interesting, Pool Doc, as I did not know that. So! I guess it's just a bleach adding Summer. That's okay, though, because the water is sparkling clear! Now, if I can just keep the birds from pooping around the rim...............
