Having problem with flow in your tank?

[gman0526]

This is by far the coolest thing I've seen so far coming out of MACNA (other than Zack's lecture) ;). this is a 6meg video from www.melevsreef.com I want 2 of those, shame they'll be ~$300.00 ea.

That moves some water!!!!! :)

Just wondering.....
When is enough, enough??? The poor corals are going to be hanging on for dear life!!! If you scaled that up to full size I don't think you could swim against that.

[gman0526]

Not really, it's all gonna depend on the kind of corals you're gonna keep. Softies and most LPS wouldn't really benefit from something like this, but SPS would love that kind of flow, remember that most SPS come from the crest of the reef where the sheer force of the waves is 100's X more that that. Also take into consideration the fact that rockscape will also affect the flow.

True, good points.
I have heard you can get pushed around when diving in those types of areas.

Are those magnetic coupled or does the glass need to be drilled?

[gman0526]

That's the beauty of these things they are magenetic!!! You can place them wherever you want. ;)

[fppf]

I kind of had that feeling.
I'm shocked it took someone this long to make an in tank pump like that.

Did they say how thick of glass or Acrl it could be used on?

[gman0526]

From their website
"The VorTech is designed to operate on gap thickness from 1/8" to 3/4"."

WOW, don't get your finger caught up on that one.
Those can erase a credit card from accross the room LOL.

I wonder how much heat is still put in the tank.
When I installed my skimmer it raised my tank temp another 2 degrees. Those pumps are all installed external so the only heat is from impeller contact and fluid shearing.

My guess would be your usual friction losses, some magnetic coupling losses, and fluid shearing. I would think the fluid shearing would be a lot less because there really is no back pressure on the pump. Its nice its all open. I'm sure Nemo wont be trying to put a pebble in that thing!

[gman0526]

According to the site there is no heat transfer at all, but everything looks great on paper. ;)

[fppf]

Yeah, don't we ALL know that!

I would say there should be far less heating than any other type pump to date.

[icereefer]

Wow those look sweet, I would just feel bad for anything that got caught in one of them. :shock:

[gman0526]

They're coming up with some sort of a cover for the blades b4 they go into production spring next year.

[FishinInTheDark]

That's an awesome pump! Looks like SPS heaven.

(Liked the blaring music too.)

Well, there goes another one of my ideas! "I shoulda got a patent"

[2639]

so...whats the actual pump: the object on the right or are both objects working in conjuction?

[Geoffrey3029]

I think the pump on the left is the finished product but the one on the right gives you an idea of what the propeller looks like.. imo
