Just how much food (frozen cubes) are you suppose to put in your tank? I have one lemon peel, a brittle star, a coral banded shrimp, an emerald crab, and about 10 snails-- I have been feeding them about a quarter of a cube every other day-- I don't want to underfeed but I don't want to overfeed and cause an increase in nitrates and pH- I am just not really sure how much food is enough and how much is too much--
