Algae Turf Scrubbers???

[mr_alberta]

Well, I'm looking at the various ways of filtration and came upon something called Algae Turf Scrubbers which I didn't know about until a few hours ago. They sound promising, but I'm not really clear on how they work, so if someone who uses one could post some pictures of how it is set up, that would be greatly appreciated.

there were a couple old threads about it and I believe some one on the board is using one. the down side they need a lit of space to be effective in relation to your tank..
