in a area that small having a DSB
is no real benefit. Add 1-2" with some LR
rubble and caluerpa. Any way you can add a 15 gal
or 20 under the stand as a fuge? I have a 15 tall under my 125 stand and I have it dump into the sump. I also have a 20 gal
next to my 55 fowlr
. Once you get them a refugium can be just as fun to watch as the tank.
