I get a lot of additives from drs foster & smith.
Corals - I feed the tank zooplex, microbe-lift all in one, zooplanktos-m, sps grow, coral frenzy, frozen cyclopese, I also shave frozen mysis and target feed a couple corals.
Inverts - I feed the tank phytochrom for the clam and tube worms and other inverts
My fish get, shrimp, scallops, mysis & nori all soaked in vitamins and garlic xtreme. And frozen cyclopese. They go crazy over cyclopese. My eel gets silversides.
I'm sure I'm forgetting something.
