To fuge or not to fuge?

[Madmak]

I've recently converted my 30 gallon refugium to a frag tank for the same reasons that Kien mentioned, biopellets killed it. Without biopellets it grew Chaeto well and helped with pH and nutrient levels. I did leave the sand bed and rubble there for the critters.

I still think a refugium is a good idea for a tank that doesn't incorporate a carbon dosing program. I would consider it essential to a tank with a small amount of live rock or one using dry rock, for at least the first several months.
