What do you have in your auto feeder?

Never has for me. They get sucked right in and blasted into the main tank. Fish go crazy chasing the food. Best thing is, any small fish have a chance too because it disperses the food throughout the tank quickly.

^^ that's why I do it. To eliminate the feeding frenzy at the feeding site. My main return pump disperses the food in 4 seperate places in the display.

 

In general, fish food that's soft and pea sized or smaller should be ok to put through a pump. larger items might be ok too as long as they aren't hard or crunchy. If they are hard or crunchy it could damage the impeller. I also don't like to put flake into the sump as the pump just disintegrates it into nothing, pellets are better. I am feeding Jan's food to my Iwaki and it says "Yuuuummmm".

 

imo: Mag drive pumps are great for this because if the impeller gets stuck, it's not that big a deal and you can open the pump up and remove the clog. The direct drive pumps could have problems if the impeller stops suddenly.

 

I don't know about a Mag12, but I've seen a Reeflo Dart turn a clown fish into fish / coral food in about 0.25 seconds. Poor guy got lost in the sump and decided the intake pipe was a good place to hide.
