So do I.. wet/dry is an exception..I have a small 500litres/hour subsystem in my sump...but all my remaining biological media is submerged and in the flow of water...
wet-dry systems have to be more efficient since more oxygen will be available to the bacteria than in completly submerged systems. You would therefore need a smaller sump and a lower flow rate.
Am I missing something with the Japanese system?
