Kreisel tank water outlet placement

[Levinson]

Hi all.
I've built a crappy rearing unit to raise my newly hatched shrimps but it failed. So I've decided to build a diy pseudo kreisel tank just in case I end up with more baby shrimps in the future.
I wasn't sure whether to post this on the DIY forum or here but thought there might be more people here who've had an experience with a kresiel setup.
I've been looking at various kreisel designs but I've still got a number of questions.

1. I've seen designs that have water outlet at the top right next to the water inlet (drawing 1), but there are other designs that have the outlet at the side of the tank (drawing 2, when the side of the kreisel is exposed and contained inside of a bigger tank) or on the opposite side from the inlet (drawing 3).
Does it matter where the outlet is placed?

2. For drawing 1, Is there a reason why the outlet is placed next to the inlet? I'm not sure if I understand its placement. It looks as though the flow is directed towards the mesh. I'm sure it works if done right but I'm worried about the flow from the inlet pushing the larvae and other stuff against the mesh.

3. Can something like Vossen's Larval trap be used to grow larvae if the creasures are small enough (or if the unit is big enough)?


4. I'm thinking of building a 'hang inside the tank' rearing kreisel tank. Would there be any potential issue with such an idea?

To answer one of your questions, the flow in drawing one is designed to keep anything from getting stuck against the screen.

I generally go with option 1.
3 may work as well.
I don't have good experience with 2.

Thanks Peace. So it's meant to do the opposite of what I'm worried it might do.

By not having a good experience, do you mean a bad experience or lack of experience?

Bad experience (larvae trap): larvae get stuck to it.
If you have a pump driven spray bar outlet or jet like I use, the screen is ideally behind the outlets so that the outflow drives larvae and food organisms away from the screen.
With slow flow outlets (air operated) the screen is best on the opposite side of the tank.
