Floating pellets allow you to monitor how much your fish are eating, helping you to avoid over or under feeding at this growth stage. However, if you overfeed, the uneaten food will produce wastes that can be harmful to the fish. There are some exceptions to the once-per-day feeding rule. Think about it: You add feed into the system, the fish eat the feed and produce ammonia, bacteria convert ammonia into nitrates, the plants consume the nitrates and grow.

To determine how much food to feed tilapia, you need to know three things: The water temperature, the average weight of each tilapia, and the the biomass; which is just a fancy word for the total weight of the living organisms per cubic foot of water, or for our purposes, just the total weight of all of the tilapia.
