My Feeding cycle in my 180.
cyclopeze almost every day.
Frozen Shrimp with cyclopese
Black Powder and Spectra Vital 1 every two weeks
Marine Snow once a week when not feeding BP or SV
Liquid food, marine Snow, concentrated bio stuff (can't remember the name... smells like bad squid) once every week.
I have sponges and feather dusters coming out of every nook and cranny. My corals are growing crazy, no noticable algea problems, no nitrate, or any other porblems...
Just watch how cold, frozen, or off the PH, Salinity, or anything can be. Never spot feed food that is "too concentrated". I have made that mistake before and it caused alot of problems.
Good luck.
