I use an automatic feeder on my bedroom tank. The tank is massively
aerated and the bubbles would normally cause the feeder to clog with
moist food but I fixed it so that would never happen now by having the
automatic feeder suspended 14 inches above the tank surface and this
feeder (a cheap penn-plax daily double) works perfectly since I have
been doing that. I've thought about trying to get an invention patent
but decided the solution is so simple and the public domain would be
helped so much by it that I cancelled the idea. I just clamp the feeder
to a long 5 inch wide 1/16 inch thick piece of glass leaning against
the aquarium so that the automatic feeder is 14-15 inches about the
tank's water surface. Works perfectly and am planning on using these
automatic feeders with my 2 bigger tanks as soon as I find a clamp of
some kind safe to use on glass and I will order some acrylic panes that
will act as a suspender so I don't have to get too much of a suspender
and also to reduce earthquake worries shaking the automatic feeder off
of being over the tank. Later!
