It should include the regular addition of trace elements, calcium and macro elements (from page 42) for the invertebrates and topping up evaporated wa- ter against strong density variations. Prepare daily portions for feeding. If you have the opportunity to use an automatic feeder, the sera feed A plus allows you to feed up to 30 days, depending on the number of fish. sera marin granules is excellently suited for automatic feeders. The soft granulate keeps its shape and floats in the water long enough to be entirely eaten by the fish.
