I do not know much about a refugium except that it is used as another tank other than your main tank that houses some insect like creatures that is suppose to clean up excess impurities in the water. But can a freshwater tank use suc ha concept? I have about 20+ goldfish in my 4x2x2ft tank.

Dear Flying Chicken,
Firstly goldfish are dirty buggers, they eat alot and shit alot and in between munch on anything that is in the water. Thus you need a very efficient filter. Sorry have not heard of a refugium before but a sum or trickle filter might be sufficient for your requirement. But even then the maintenance is quite often as the fishes are really dirty
Something about the water & the fishes that calms me down.
Yeap, they eat and shit ALOT! A sump filter would be best but i believe you didn't have one so you next best bet will be a eheim 2228, 2028 or even better the wet/dry 2329.
My new tank has a sump that comes with it. As the sump is pretty big, I am thinking of converting part of it into a refugium that is what normally reef aquarium do. However, same as micheal lai, I'am rather clueless about a freshwater refugium and its benefits, so I'am asking the gurus here!Originally Posted by aquarius
a marine fuge has liverock rubble (some use dsb), macroalgae to absorb nutrients. with no predators like fish, pods will multiply well. pods help to clear detritus, algae,etc. some hobbyists culture these pods to feed their fishes eg mandarins.
a refugium is really just a refuge for these pods from predators and a place to put these macroalgae. not very nice to have these macroalgae in the main tank right?
just stay with a normal sump. if you want something in it to absorb nitrates, you can dump a bunch of hornwort in it. no need too much cos they grow real fast.
what you want to achieve is to remove nitrates from the water (assuming the filter media is able to break the ammonia down to nitrate fast enough) and not have a place for critters to grow. nothing beats regular water changes though
