Algae scrubber

[Money pit]

Ok so having been out of the hobby for a few years, there's quite a bit that I've forgotten. I decided to spend a good part of the long weekend refreshing my memory, and learning whats new in the last few years. I checked over at Marine Depot to catch up on both Calfo and Bornemans forums. Sad to see they are both closed now, but at least they are still available to read. Anyone know if these guys are still active somewhere on the internet ?
While I was there I came across this huge 95 page thread on algae scrubbers.

Some very interesting stuff. Apparently this is thread #2. #1 was started on RC.
The real reason for this post was to see if anyone here has given one of these a try, and if so how it worked out for them. Seems very basic and simple.
