K kaspm New member Nov 3, 2006 #1 I have a 30g tank, that I will be drilling an overflow for. Before I do that I am trying to figure out what size bulkhead to use for flow. What amount of flow do you recommend for a tank of this size? Right now im planning on keeping some zoos and some smaller fish.
