I was considering a HOB
fuge to go in my sump, but have decided against it now, in favor of build my own out of a rubbermaid tub or maybe a bucket of some sort. Going the simple, effective route as well. A powerhead in the sump will bring water into the fuge, will let gravity do the rest, placing 2 bulkheads to return the water back to the sump.
I have not finalized my plans, but I decided I could get more space out a DIY
fuge that I could on a 12" or 18" HOB
fuge. I don't think they are a bad idea at all, just not what I wanted in the end.
Do you have a sump already? If so, have you considered a DIY
type setup or do you want the simplicity of a HOB
I'll let someone more experienced answer the ligthing question, but I plan to run my fuge lights opposite of my tank lights.
