I'm a fan of a spray bar on the return, I'm using irrigation pipe sort of like
this thread on RC but without the nozzles. It gives great flow down the back and out to the front under the live rock.
But.... it's not enough flow on it's own.
If you don't like the look of powerheads there is the
Tunze streamrock option as well.
I have 5 anenomes that have never wandered near the Tunzes.
