Koralia powered DIY canister?

I'm amazed how much water Koralias can move, for very little electricity.

My Koralia clone moves 1,321GPH for 12 watts. By comparison, my Magnum 350 moves only 350GPH for 35 watts.

Some of that difference is due to the resistance of plumbing and filter media. To be fair, eliminate those. What's left is essentially a powerhead, and Koralias still beat the pants off of any traditional powerhead I've seen in terms of efficiency.

Ignoring the difficultly of actually building one, could a Koralia theoretically be used as the pump in a highly efficient canister filter?

Or are there any commercial canister filters taking advantage of this?

The hardest part about making a canister is making things water tight and finding an appropriate container.

I would definitely look into it for a diy pond filter where leaks aren't an issue.

a koralia is just moving water, its not pumping it.

If the koralia would be pumping water from or to a canister filter, it wouldn't be pumping almost no water at all, heck, it could probably never pump water up for more than half a feet.

The design of a koralia would basically make it impossible to "pump" water. It sucks from sides, moves to front in a broad pattern. They aren't designed with any head in mind and I don't imagine it would fare well.

Like you mention, the difficulty to seal it would make it hard... or impossible. Particularly to seal it under pressure. I definitely do not think it would be in any way efficient.

When you enclose the sides to pull water from a defined source(intake) you'd reduce flow all alone. Then put the back pressure on the broad flat blades of the impeller and you'd really reduce it. NOt to mention the mechanical deficit on this design.

You have to realize that the head height of a canister and the logistics of pumping through media and in a STREAM change the filter greatly. Mag 350's are pretty old too....
I think that the "flow" rate of a koralia is slightly subjective too.

They're great water movers, but are not "pumps".

Makes sense, and also explains why they're more efficient than a traditional powerhead. Thanks for the explanations!
