So far, the only other needle wheel I have found is an Ocean Runner pump. There is a Turbofloater that comes with one. I know there is another though. If interested in the Oceon Runner, contact AJ at

JoJo has a good point also. I assume she means with no needle wheel. Some people have run their Euroreefs, with a standard Sedra pump, instead of a needle wheel. They have produced the same results. {so they say.} If you could borrow a few pumps, like Mags to try, may be worth while.
