How much is too much? I feed a pinch twice a day. The fish eat every bit in about 2 minutes. I have a clown, Coral Beauty, Cleaner Wrasse, Bangii Cardinal, Mandarin Dragonet, Lawnmower blennie, and a mix of hard and soft coral, and some inverts, starfish, cleaners ect. 75gal w/ refuge and 20 gal sump. Proble is my nitrates. They're way too high. (30-55 PPM) It's obvious that my feeding is off. I was just going based on the recommended times in the 'salt water fish' dictionary!! How often and how much should I be feeding? I never see the Bangii eat.. the others seem to get it all!! And how often should I be feeding my corals the invert banquet??.. Been doing about 2.5 ml's twice weekly. HELP PLEASE!
