Is a 10g refugium good enough to keep my 20g tank clear and healthy. I have no other filter running now. I just got my fugi going and worried about keeping the middle and bottom clean because my overflow is just skimming the top.
Is it a sump/refugium or just a refugium either way id say thats good since a tank that small doesn't really need all the other types of filtration as a larger tank unless you are planning on corals which in that case a nano skimmer would be great
*edit* you do have something else moving the water too right? Like a powerhead or circulation pump..you should have enough flow that stuff does not really have a chance to settle on the floor
