Excerpts from Paul Baldassano's Reef - 40 Years in the Making ...

"Since I donít want the algae growing on my corals, I have built a five-foot algae trough. [Editorís note: This is a filtration system known as an algae scrubber, with algae reducing nutrients in the tank.] It is a plastic trough that is positioned at the tank's surface along the rear. It is positioned partially under the main metal halide lighting, and it shields the tank's back glass from light, giving the tank a much more natural appearance. The trough provides favorable algae growing conditions by having swiftly flowing water that is only a half-inch deep and located a couple of inches from bright light. I also installed a cement-encrusted plastic window screen (algae loves to attach to cement) in the trough which can be rolled up, removed and cleaned. What more could algae want? The trough is fed from the skimmer's outflow, so it uses no power and takes up no room that I would use for other things. It is also practically free to build one using a PVC fence post sliced in half. "

I would say ATS folks are winning the battle ...
