Wouldn't something like this work as well?

Pictures of my mod
The flow is definately better than any of the powerheads or closed loop system that I had in there, it just doesn't reach as far as I was anticipating. It very well could be my choice of propeller. I found that if I attach it to the back wall of my tank, and with the modified bracket I made, having it angled slightly downward does create nice turbulance off the front glass. My anthias actually enjoy swimming in the current.
I guess I was just expecting substantially more flow from this than what I am getting. Either my goals were too high, or my prop is too little.
So far, so good though... No noise, and it always fires in the right direction.

It is a left hand prop.. I thought the nut (grooved) side of the prop was the "out" side of the prop as it would have to be if this was on an RC boat. In "could" flip the prop to see though.

Prop has been flipped... Waiting for epoxy to dry.

Flipped it around, and not too much increase in the flow. There was some, but nothing all that dramatic. Still very good though.

GOt a querstion for yall, are your mods a little noisy? Maby I need to recenter or take some slack out of mine but its a little noisy for my taste. I did this on a MJ1200 thought so that might account for it. Got it in and running on my wavemaker timer and the noise was pretty noticable. No chatter on start-up... just opperational noise. Sounded like a little outboard in there.
Sounds like your impeller is off centered even slightly. This can generate a lot of noise. This mod should be pretty quiet actually even on a MJ1200.
If you want to make it really quiet, you might even consider balancing the prop like somene suggested previously. A propeller balancer can be bought from a hobby store easily.

Here is my suggestion if you think your mod isn't producing enough flow. Fill up a sink or tub, take off the pvc guard and try and run it without the guard (hold one finger on the end shaft to keep the propeller assembly from flying off. This will show you the potential of what the mod can do. Then try it again with the pvc guard on. This will show you what your mod is actually producing. After that you have to figure out why their is a difference (if there is one).
On my mod I noticed the largest problems because the outflow hole was not large enough not the inlet holes. This might be caused by the propeller being set to far inside the guard or a couble of either things. I really am not sure how to fix it yet because I haven't tried. But like I said above, if you arn't seeing a substantial increase in flow take off the pvc guard and try it agian in a sink or a tub.

Kevin is right on with his comment regarding the PVC housing. This will make or break your mod so to speak in regards to flow.
Hint, the idea here is to have enough space and water inlet holes behind the propeller blades so that water can be sucked in from behind and forced out the front accordingly. I also find that if you balance out the inlet holes on all sides in terms of number of and spacing, the flow is much better and more uniform. And it looks better too

I have some of the perforated PVC to which melev posted a link. I use it as a strainer for my U-tubes. I'm not so sure that it would allow more flow as the larger drilled holes in your PVC fitting, or will it be as sturdy.
