I have a 2 gallon aquarium that I keep my guppy fry in. They are constantly swimming. My filter puts a lot of current in the tank and I was wondering how I could reduce the flow. So my fry can rest. PLEASE HELP!!
You need a flow diverter of some kind. I built one for my Eclipse tank. Not sure how to go about it with your filter but the idea is sound. Put something in front of the outflow to disperse the water returning to the tank.
