Maxspect Nano Tech Bio Blocks
Maxspect’s Nano-Tech Bio-Blocks are a durable, dense arrangement of small spheres that create an ultra-high surface area media. This design reduces the volume of biomedia needed for efficient nutrient cycling in both fresh and saltwater aquariums and ponds.
The ceramic media features a cross-cutting surface area that provides an ideal surface for a dense population of beneficial bacteria. These bacteria help remove ammonia and nitrites from aquarium water. Some systems may also observe a gradual decrease in nitrates with prolonged use.
Suitable for sumps, reactors, trickle filters, wet/dry filters, hang-on-the-back filters, or direct placement in the tank.

I’ve used these bio blocks in my saltwater tank for six months. The water clarity has improved significantly, and I notice less ammonia spikes. The blocks fit well in my hang-on-the-back filter and don’t clog easily.

The surface area is impressive. After installing them in my reactor, my nitrite levels dropped quickly. I didn’t need to add extra media, which saved space in my sump.

Great product for a compact setup. The ceramic structure holds bacteria well and maintains performance even after several months of use. Works perfectly in a freshwater pond.
