Agree bro. Sometimes these bubbles can pop quite high. What if one small egg got pop over to the dry portion then xxxx...

The smaller base of the chamber compare with the top is to prevent the eggs to be siphoned. If the base is bigger then top, it would act like a gravel cleaner, you could imagine the eggs got suck up and held on top mesh. anyway, your idea may be better, hope to see your practical implementation

Check this out although they were fish. Must bear in mind that shrimplets & fries are different in size and resistance to the current flow that they could take after hatched.

It's a video on egg tumbler. Actually, that was a commerical product. Came across such product about 2 years ago but not cheap. Noticed that the broader base did provide better tumbling effect, but slightly more difficult to build as it is hard to find readily available clear material to fix everything up.

Ya, I have that happening when I use a BIG net and stuck an airstone inside to bubble the eggs...next day, half the eggs are sitting on the frame of the net, dried

The top tube section should be smaller than the base. The broarder the base the better it will be. What we want is to create an unbalance flow effect inside the base chamber in order to create the tumbling effect, much more easier to control than having a straight long tube regardless of the size in diameter.

hehe, you may want to check with shrimp eggs with tapped up, tapped down or straight chamber better. for me narrower base work overall well. you can forget about how well it tumble, if they can sucked n top mesh, and i guess you can visualise smaller top or bigger top work better to prevent the egg get sucked.
