We already make a 1/4in RFG - perfect for 5 gallons and below. I run a small 5-gallon fluvla Spec V here at the office with just single RFG and our Fluval Spec V adpater. We also recently discovered this Nozzle/Adapter combo will also fit the Imagitarium 3.7 Gallon Pico. I'm in the process of planning a small rock flow display in itI just suggested a pico reefer contact you. Since you're here...any plans on making anything for pico tanks? There seems to be a gap in traditional equipment for flow.
