Overflow Boxes

[dylanjs]

How do you reefers feel about attaching an overflow box to an Eheim 2026?

Other than housing carbon or some other media, not too many reefers use a canister filter.

I don't have room for a sump, so I use the canister for carbon only.

It's good that the Eheim sucks water in from the bottom of the tank 'cause the skimmer gets it from the surface. Maybe I'll skip the overflow box.

I heard a canister filter is good for FW aquarium only. It would produce a lot of nitrate which it should minimized in a reef tank.

As long as you clean it out every 4 weeks or so, it's fine to use to run carbon. If you leave it for extended periods, crud will build up and become a source for nitrate production.
There's no need for an overflow.
