sand?

do you have to have sand in your fuge? If I have nothing rooting, why do I need it?

Most put a deep sand bed in the refugium for it's benefit's and to keep from looking at 6" of sand in their DT. Macroalgae such as Caulerpa does put down "root's" so some sand may be needed for it. If not using Caulerpa then it's seem's pointless to have sand in there but I could be wrong about that.

+1, you don't NEED sand in your fug since you are using chaeto. Chaeto provides plenty of cover for all the little critters. The only benefit would be utilizing a DSB to provide small scale denitrification which requires quite a bit of time to take effect. If you have some extra sand laying around and don't mind a thick bed, you might consider a DSB.

I have DSB in the DT... cool... I think I will leave it out!

I took the sand out of my fuge during my last water change and haven't seen anything negative from it. The drain into my fuge kicked up the sand and it ended up in my display. Not a problem any more.
