My light (Coralife 50/50) is on a timer for 9.5 hrs a day.
The feeding is kind of irregular because the tank is at my work. Some days it's twice a day, others just once and occasionally they'll get fed every other if I'm not around.
What I feed is any combination of pellet, flakes, mysis, brine, or spirulina brine marinated in garlic.
About once a week I'll chop up a raw shrimp w/ garlic or sinking pellet for the inverts.
It's a 90g with 2 clowns and 1 Tang so I only PWC about 10g a month.
