UV sterilizers are a waste in my opinion, they may get some of the free floating ich but most of the ich is in the substrate, on the rocks, on the fish, etc...
They are not a waste of time---
True--- most ich lives in the sand/substrate...however, they have to swim up from there and attach to a fish to get them sick. IF you have good water flow- the steralizer will take a hefty percentage of the ich out of the water permenantly.
Steralizers effect 2 stages of ich-
1. The swim from the gravel to the fish
2. The drop from the fish to the gravel.
I would definately rather have a steralizer then NOT have one.
Steralizers also cut down on the amount of algae growth as well.

I saw some talking about them not comming with pumps... thats true- my turbotwist did not come with a pump or tubing.
I have an Ehiem Ecco canister that I run on the 75 gallon that I hooked the steralizer into on the exhaust with a t- valve so I could control flow. I basically split the eheim exhaust and it has a tube leading to the steralizer after the valve and then to a second 'J' hook that dumps the water back into the tank. Ill see about taking pictures.
I think the eheim is supposed to dump 240gph on a good day. I reduced flow on the steralizer side until i got 25% of the other lines flow. No ich for me.
