Its huge, but Current USA makes a HOB style T5 bulb UV clarifier with a powerhead which pumps water from the tank through the UV chamber and back into the tank. One option you might consider is "borrowing" or renting a UV unit from a pal in the area, much like you would for a diatom filter. A diatom filter is another option, though sometimes GW comes back for me after a diatom. But I imagine the Turbotwist could be rigged with a powerhead pump that would do the same thing. And its probably nice to have a UV clarifier around for a new tank or rare GW outbreak. You could also beat it with a radical 4-5 day total blackout... with a 75% water change, charcoal, nitrazorb sponge in the can filter cure. I did that before ever becoming a UV clarifier convert. It works, but is hard as heck on the fish and bacteria colonies.
I have my clarifier plumbed in line and never ever use it, but its there just in case. I think the consensus is the turbotwist is the best bang for the buck. I wish I had bought that instead of my Current USA. The Current is more powerful. But so what, it doesn't take a lot of zap to kill GW. and the turbotwist works, is cheaper and smaller, and fits better under the stand if a permanent install. Goodluck.
