I am looking at setting up a system for growing algae out of my display. I have a refugium, but I don't feel it is big enough. I don't have much more room under my tank to set up something different. I saw a thread on here a while ago that I can't find now where the individual had set up a flow of water along the back top rim in a self made container, along the whole rim. The displays lights supplied the light and I think they set up a pump to supply the water at one end and there was a hole at the opposite end that drained back into the tank. It was only about 3-4 inches wide. I have an enclosed top so it wouldn't be seen. What I was hoping to find out is how much water flow I should have. Has anyone else done a similar setup?
