Auto feeder for fine pellets

[MitchM]

With an Eheim you can't tape the opening.
I use the Eheim for flake feeding.
I also have a Rena and it works well for fine pellets.

Eheim twin is a corkscrew feeder.
Eheim also makes a single chamber that could work for you.

I have been using a Rena for pellets and it usually works out pretty well. Occasionally it will do a big dump.

Hopefully some big company will take building a good auto feeder seriously and come up with something brilliant.
