I am going to be adding a refugium for sure but am not sure where to put it. I think I basically have two options; below the tank or a hang-on unit.
I like the idea of the hang-on unit because its a simple overflow back into the tank instead of the 'spinning blades of death' return pump. However I'm worried about the size of a hang on. I saw
this hang-on at
premium aquatics, its a little less than 5 gallons. I have a 55 gallon tank with no current sump or DSB. I would like to add a minii DSB to the refugium and cultivate flora in there (duh). Will this size be sufficient if I run the ref lights eiither 24/7 or opposite cycle??
TIA
