How often should you change Rowa and Carbon in a sump and a canister also.

I’ve spoken to a few reef keepers in my area and they all say different.

I have 450ltr custom tank with sump and bio gro

And

I have a 100ltr with fluval 305 canister.

Thank you

Unfortunately it’s a difficult question to answer because most of what carbon removes isn’t really detectable, so you can’t test for it.

BRS just did a video on this. Their method seems as good as any.
