Fluval BioMax Biological Material Remover, 500 g - Biological Filter Media for Aquariums

The Fluval Biomax Filter Media is a popular product among aquarium enthusiasts. Customers have praised it for its surface area and efficient bacteria colonization. The media can last forever and requires rinsing in tank water, but Fluval recommends replacing it every six months. Some customers have mentioned using other products from different manufacturers for better results or when using hob filter configurations. A customer even asked about using it for drinking water, to which another customer responded that it's only good for building good bacteria in filter systems and can do nothing for drinking water. One customer was unsure of its effectiveness as they have just put it in their tank. A reviewer has also mentioned that there are better options available, and the media is overpriced. Despite that, most reviews showed that the Fluval Biomax Filter Media does its job and holds beneficial bacteria, keeping the water crystal clear.
