The scrubber in the pic is what they look like when new and in one piece. I did buy it used from an acquaintance in the US and thats the pic he sent me when I was buying it. Mine arrived smashed to bits. Great delivery service. Without getting into it, getting any satisfaction from the delivery was hopeless.

So we built an ugly glass body for it, as was behind a wall on my tanks anyways. Worked exactly the same. I would have to go find some pics of it working on my 225g, as I no longer have them but would guess they are on the boards out there.

The screen pic is from my use. Anyways, for the surge, the screen sits on a pivot and when it fills with water, tips and dumps out the chute pictured on the scrubber. They were designed, so they could be used as the main and only filter sitting on top of something like a 120g with a halide hood in the front of it. No sump needed.

Of course they could be used in any application. including being run into a sump, but then the surge benefit is loss, which is what this thread is about. When we discussed them, back in the days, , many of us, including Eric, thought the surge could have been a lot more. I ran it with several pumps, including one that had it dumping twice/min. which made for an interesting little surge.
