I would try fish chunks, scallops or any saltwater mollusks, squid, etc. thrown in a blender and pureed.
It'll feed everybody in your tank pretty easily.
If you don't puree it but just blend until it's in small chunks it will feed the fish and large inverts as well. I also throw in a couple multi vitamins and a packet of gel so it will stay in large pieces. Most people skip the gel but I like it. If you have herbivores, put in some nori (seaweed) too.
Been making my own food for years. It's the only way to go IMO
Other than that, Kent coral products are good.
