Joe's Aquatic World stocks a huge selection of biological tank cleaners for freshwater aquariums.

A biological tank cleaner biologically activates your freshwater aquarium using nitrifying bacteria, which will give your freshwater aquarium the best possible start.

A biological tank cleaner can also be used to replace bacteria that are lost after water changes.

We also provide a range of freshwater oxygenating tablets for freshwater aquariums.
