Kreisel Tank Design

[nacra99]

Does anyone know a good design for a Kreisel Tank? (the kind that spins water round and round to keep it's inhabitants suspended in water)

I'm thinking of building one out of a 10 gal tank, but have yet to find a good design.
I know they are available commercially. But i'll have to sell my kidney to be able to afford one of those.

I'm lookin to experiment with breeding lower order shimp which requires the larvae to be suspended in water.
Might also be useful later if my seahorses decide to get frisky.

Tanks! (so to speak)

Ok.. well i had nothing better to do Christmas eve... so i decided to build the kreisel.

I have an old 10 gal lying around and an empty 5 gal water cooler jug so i thought i'd use those:

Next, i hack of the top and bottom of the water jug so that i have a cylinder.



Then i cut a section out of the circumference which will eventually the open top of the kreisel.

Next, a hole is cut out of the cylinder. This will be the water outlet from the main brood chamber.



And then a fine mesh over the hole to prevent the inhabitants from escaping the brood chamber.
I used a larger mesh for this particular one because i'll be using it for my Reidi Seahorses. The one for the shrimp will have a 44 micron (rotifer) mesh.
The "Glue" is 2 part epoxy. Not very pretty.. but hey.. it works.

Here it is in the 10 gal, waiting to be siliconed to the sides.

Re: Kreisel Tank Design

Looks good... i think.....

Re: Kreisel Tank Design

looks good!

I was expecting the water movement to be slower... but Thats more a factor of the pump your using then anything else.

I know this is for freshwater stuffz .. but since i've started it, i thought i'd post an update on what my kreisel tank has been doing since the build.

I know this is a really old post but did any of the fry make it? I have attempted to raise seahorses before but never got them on to foof larger than baby brine and they would die after reaching about 1/2 in length.
