Does anybody knows if this can be hanged outside of the tank/sump?

Ya it can be in sump or hage on it even says on features of the reactor:lol:

I know i can hang it the question is can it be outside the tank?:)

Yes it has to be outside. I believe

Wendell has stated he is testing the unit on a high end SPS system.
you might want to give him a call to see how it's working out

I would have loved someting like that when I had a 75 going

I did some internet searching (found on e-bay) and it CAN be hanged outside . the pump is build inside the top cover. the question now is, do i need a feed pump or it is self priming.
