PaulB bbs feeder issue

[squatchaquarist]

I built a PaulB designed BBS feeder for my future mandarins. In a trial run, it seems that the BBS are not making it all the way down the tube into the feeder and start rising back up with some air. I cut off the funnel because I suspect it was too far above the water line. I’ve also sucked air out of the container with a turkey baster but still cannot get the brine naups to go all the way into the container.

I suspect it’s a pressure issue but how do I fix this?

Follow with tank water to push them all the way down. Or even just air, but I use tank water

Am I supposed to drip the BBS "dry" into the funnel first? Then follow with water/air? If I take the feeder out of the water the BBS goes down no problem, but I'm sure that is not really the point of this thing!

What I do is drain the hatch into a syringe with the hatch water. ( Which is the same sg as my tank,)
Squirt it slowly down the Ridgid airline tubing I used and follow with some tank water if I need to.

Usually I don't need to.

I’m not sure what changed, but I got the little babes to travel down the funnel like they’re supposed to!

Thank you for your help
