I have a 55g dt with an hob skimmer and a Fluval 407 cannister. Having trouble keeping nitrates down so I'm thinking of adding a refugium. I could buy an hob for a bit more than $300 plus another $100 for the stuff to put into it. But I've got a 5 gallon tank that I might be able to use to build one.
Your suggestions would be appreciated. I'm thinking of putting the refugium under the tank and just running input and output hoses between dt and refugium. A gravity fed line to bring water down to fuge and a pump to pump water back up to the tank. Add a light and some emergency one way valves in case of power failure and it should work.
My question is, will such a simple setup actually work? How big a pump would I need? Any other additions or subtractions to the plan?
