I find it strange because I feed the tank a decent amount 3-4 days in a row and will take a day from feeding in between. So I am not sure why unless I should turn the protein skimmer off again... I used to feed the corals directly, but at this point I do not anymore with a turkey baster. I end up mixing the mysis, oyster feed, and spiraluna mix together and feed it all at once... The light is as high it can go with the AI Prime 16 stand and the hammers are both roughly 3-4inches from the bottom (glass not sandbed) from the tank. The calcium is the only thing I dose, but only when necessary since I have 16 corals, they are 5 zoas, 2 favias, 3 favites, a duncan, a winter's pipe organ, hairy mushroom, galaxea, andthe two hammers...
