The replacement sponge for the Aquael Versamax Hang-on Filter Range is an essential component for maintaining effective filtration in your aquarium. Designed to fit perfectly within the filter unit, these sponges offer mechanical and biological filtration:

1. Mechanical Filtration: The sponge traps debris, uneaten food, and other particulates from the water, ensuring it remains clear and free from floating particles.
2. Biological Filtration: The porous structure of the sponge provides ample surface area for beneficial bacteria to colonize. These bacteria are crucial for breaking down harmful ammonia and nitrites, thus promoting a healthy and stable aquatic environment.

The replacement sponge is easy to install and should be rinsed regularly in tank water (not tap water) to maintain its effectiveness. Depending on your aquarium’s bio-load, the sponge may need replacing every few months to ensure optimal filter performance across the Aquael Versamax range, including the Mini, FZN-1, FZN-2, and FZN-3 models.
