Hello I have a 27 gallon tank with a HOB filter and a few powerheads, and I wanted to replace the HOB with a sump, so I went out and bought a used overflow box and I already had a 5 gallon tank (only thing I could fit under the stand). MY question was is it still worth installing this sump, will that extra 5 gallons still be benificial??? If it still would help can some of you give me a few good brands for a return pump and any ideas on how to do the return plumbing (spraybar, nozzle, ect..). And one last thing is it possible to turn it into a refugium????
thanks
thanks
