    Fishless cycling is a form of "maturing" an aquarium.The goal of the process is to establish a robust colony of nitrifiers, with the ammonia source provided to allow nitrifiers ('beneficial bacteria,' although nitrifiers can also be archaea) to grow and reproduce coming from non-fish sources, hence 'fishless.'

    The timing and application of these multi-part fertilizers should coincide with a plant's growth stage. For example, at the end of an annual plant's life cycle, a plant should be restricted from high nitrogen fertilizers. In most plants, nitrogen restriction inhibits vegetative growth and helps induce flowering. [71]

    en.wikipedia.org/wiki/Aquarium_filter

    Prefiltered water is delivered to a perforated plate (drip plate). Prefiltering may take place in the aquarium via a foam block or sleeve in the overflow, or weir siphon, or it may be prefiltered by filter wool resting on the perforated plate. The waste laden water from the aquarium spreads over the drip plate, and rains down through a medium.
