Surge tank experience?

[Pescador]

I haven't tried one myself, and I realize your looking for hands on experience. but...
You probably have already done a search for the Carlson surge device.

Here's one link http://petsforum.com/personal/trevor...ge_device.html

The Dana Riddle version uses a 5 gallon tank.

There's some info (8 pages) in The Reef Aquarium Vol.3. If you want to see it let me know.
