So this really is not 100% DIY. I bought a Ehiem Auto feeder and for over a month I could not figure out how to mount on my marine land 300. While adding egg crate to my over flow to keep snails out yesterday day gave me an idea on how to mount my fish feeder. I removed one section of glass top and cut egg crate to fit in that area, then I cut out an area for the clamp to clamp onto and for me to be able to remove the feeder, next I cut out area under the food holder so when it rotates it won't hit or have any issue. To keep the food contained while it dropped into my tank I took a plastic cup and cut it in half and zip tied to the egg crate. As I was writing this up I thought why didn't I take pictures as I installed it.
