really, all the places i've read about refugiums say atleast 10x the over all system size :S maybe that was with a DSB in it
algae only needs contact with water to work. fast or slow flow, it will work exactly the same. if you needed to run water through the refugium that fast in order for it to be efficient, you would actually see the plants absorbing nutrients, and they would be growing visibly, before your eyes.was yours a sump refugium?
i guess in a way if the water sits in the refugium longer the chaeto and DSB can suck out the nitrates in larger amounts then a higher flow would.
they claimed that a DSB works better with passing water
