I have a 180G mixed tank with a pink tail trigger(3in), blue hippo tang(3in) yellow eye kole(4in), queen angel(3in), 5 barred goby(3in), 2 ocelaris clowns(1.5/1in), 2 anthias (2in), 3 wrasses (4,2,1in) and a mandarin 3in. I only feel 1 cube frozen food 2x a day and a 1/2 sheet of nori. but my nitrates are 25-30. does this jive? are there too many fish? I dont feel like this is too much food (they are all fat). but for 3 weeks same nitrated. they vary between 25-32. Tank has been set up for 10 months. pH-8.02, sal-1.025, alk-11.0, Ca 500, Mg-1230, phos- .03. dose brightwells a/b and all for reef every few days.
