Maxspect Nano Tech Bio Blocks (2 per box)

Maxspect’s Nano-Tech Bio-Blocks are a durable dense arrangement of small spheres creating an ultra-high surface area media which reduces the volume of biomedia actually required for efficient nutrient cycling in both fresh and saltwater aquariums and ponds. This unique ceramic media has a cross-cutting surface area that creates an ideal surface for a dense populations of beneficial bacteria that remove ammonia and nitrites from aquariums water. Some systems may also notice a decrease in nitrates with prolong use. Suitable for sumps, reactors trickle filters, wet/dry filters, hang on the back filters or directly in the tank.

The Maxspect Nano-Tech Bio-Media is developed using established technology borrowed from the sewage treatment industry with a proven record of nutrient removal of waste water. Instead of using mounds of costly live rock within the aquarium for biological surface we now have the option to regain more space and less weight in our aquariums and sumps.
