Regular maintenance is important for keeping your aquarium healthy. It is generally recommended to replace filter sponge media every 12 - 16 weeks, depending on tank load and water conditions, to help maintain optimal performance and reduce the buildup of trapped waste over time.

In between replacements, the sponge can often be rinsed in used tank water to preserve beneficial bacteria while keeping filtration effective.
