Frozen is more healthy for fish and does not add significantly to phosphate. Pellets add more phosphate to the tank. You can feed your corals vitamins to raise phosphate or dose neophos which is what I did. If you have a reactor zeroing out your phosphate perhaps you need to take it offline.What would you do to fix 0 phosphate? Turn off my phosban reactor or dose phosphate ?
I am really surpristed that feeding 4+ cubes of frozen food in my system every day for a month that im not registering any phosphate on any tests. . .......... seems really bizarre .
