Hi, been getting conflicting stories.. I am in process of setting up a Nano tank. I have been advised I dont need a filter, just to run a Koralia and skimmer etc, apparently the live rock/sand etc will cleanse the water, along with the skimmer. I have an FX5 and a 50 Gallon tank. The guy who gave me advice owns an aquarist shop in Glasgow and I do trust him, his overall knowledge of fish etc is genrally well regarded.
