Bio balls with their immense surface area per square inch serve as great hosts to beneficial bacteria in aquatic biological filtration systems. In trickle systems the bio balls promote gas exchange and increases oxygen levels.
They are really simple to use: place into a mesh bag and drop into the pond filter.
