Could remove the cupFirst time I've struggled with low nutrients.
5 fish in 100g and I feed heavily 4 to 5 days a week. I stopped cleaning the filter socks and dialed the Skimmer back to dry skimming. I would shut it off completely if it wasn't for my chronically low pH.
I feel pellets twice a day, two 6"x6" squares of nori a day and a cube of frozen mysis every other day. Reef chili target fed once a week and acro power once a week.Could always feed the fish more often per day, or broadcast feed powered/liquid coral foods.
Good video for if anyone thinks they can keep a yellow tang in a small tank
