how much to feed without increasing phosphate levels?

[Bravepickle]

hello everyone to be honest i feel stupid asking this question but I'm a bit lost
i have
2clown fish (juveniles)
2 firefish
1 bengali cardinal (juveniles)
i feed 1 whole cube of artemia every other day and I'm struggling with phosphate increasing by two folds should i feed half a cube a day to maintain phosphate levels and keep my little friends well feed

I find feeding more frozen than freeze dried will help keep phosphates down. Frozen actually is a lot of water but the food is fairly nutritious and good for the fish.

I feed 5 cubes of frozen daily for 42 fish. About 1/2 that on weekends.

Ok. So what size tank is this? Skimmer? What other nutrient export. For something frozen like PE mysis, for example, let it thaw and drain off the liquid before feeding.
