View Full Version : Small HOB fuge, DSB or no?

02/01/2006, 02:31 PM
I just got the largest HOB fuge I could find. It is 24.5x4.5x12 and will be on my 72g reef tank. The tank only has a 1-2" sand bed. I know I want to grow some macro in the fuge but would a DSB in that small of a fuge help or just tank up valuable space?

unless the tank is BB, i would say don't waste the space in the fuge with a DSB. You can use the space better with LR rubble or macro growing space.

The tank is not BB but a 1-2" sand bed will not help with the breakdown of nitrates. I"m worried that nitrates may accumulate in my tank if I won't have some sort of anerobic area to break down nitrates.

A sand bed in a small fuge isn't going to do anything except provide pod habitat. A good combination of chaeto and caulerpa will reduce PO4 and NO3 in the tank...
