UNS Bio Block

The UNS Bio Block is the perfect addition to the aquarium filtration system. This block provides ample surface area that serves as an optimal habitat for nurturing beneficial bacteria. The presence of these beneficial microorganisms play a crucial role in biological filtration and serve as a key indicator of a well-established, cycled aquarium. This type of bacteria is responsible for breaking down harmful substances into nitrates which are less toxic to the environment. The UNS Bio Block comes in a pack of 3 and its small size can be easily incorporated into any filtration system!
