Well, playing around with shapes for larvae tanks. I had this unit for rot cultures (with an air pump) a while back. I added a large diameter pipe in the middle of the tank. Even with leaving the neck open, the flow dynamics were pretty darn good. I would assume that plugging the neck would make it work better. The example creatures in there are RN Arctipods (so largish, heavy, and not alive) and the flow worked pretty well at keeping them up in the water column. At least the ones that didn't have trapped air and wanted to float. Not much you can do about them.
The lower third of the container even had a decent kreisel-type flow. I still need to figure out an overflow up high and the fact that it's only a 5 gal. container is working against me. The mesh screens on the overflow will have to be relatively small so the water movement would be more concentrated. I wish they were 20 gal. If anyone knows of a container with a curved cone like the water bottle but in a larger size, please let me know.
I certainly need to also rig up a system that can hold the center tube in place while still allowing for small adjustments.
Thanks!
