So I have had my Algae scrubber running for a few days now, and have a bit of algae growth already on the screen. As suggested I moved my lights to be more directly in front of the screens. But I am still having the problem of water flow.
I have a mag drive 5 pumping the water to my scrubber from the first chamber in my fuge. The first chamber is fed from the overflow box on the back of my tank. The problem is that the flow from the tank doesn't come in as fast as my pump pumps it out. I have a ball valve to control flow (though its really hard to turn!!) but if I turn the flow down so the first chamber doesn't empty, then the water doesn't flow fast enough over the screen. Any advice??
