Can I get algae if CC = 0?

[NHPool]

Hi,

We've done an OK job maintaining FC - actually, we probably haven't kept it where it needs to be given our CYA level.

In any case, we did a drop test and show CC = 0...hence my question:

"Can I get algae with CC (Combined Chloramines) = 0?"

Thanks!

Brad

Although a CC of > 0.5 certainly indicates a need to shock, a CC of 0 doesn't mean that there isn't a problem.
