While I think that's probably a really awesome system to slowly feed their fish... it also seems like a lot of work each day and it is pretty big.
Also when I feed, I have my return pump shut off and the other wavemakers go at a low rate to ensure the fish can "find" the food. With that I would have to leave everything running which makes me wonder how much would go to the sump because the fish are busy swimming around and don't see it?
Personally I like this one the
Innovative Marine AUQA Gadget Gourmet Defroster as it "slowly" defrosts the food. Not as slow as that, but slower than dumping it in. I also have my Neptune Auto Feeder go 4 times a day for a very small amount (and it shuts the pumps down)
