Maxspect Nano-Tech Bio-Spheres 1kg
Maxspect’s Nano-Tech BioSpheres 1kg feature a durable, dense arrangement of smaller 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 has a unique 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 reduction in nitrates.
Suitable for use in sumps, reactors, trickle filters, wet/dry filters, hang-on-the-back filters, or directly in the tank.

Dylan Martin –
I’ve used this media in my 120-liter saltwater tank for three months. The water clarity has improved significantly, and I noticed less ammonia spikes. The media fits well in my hang-on-the-back filter and holds up well under daily use.
Liam Dowd –
Installed in my sump filter. The surface area seems much higher than standard ceramic media. Bacteria colonization is faster, and water parameters have stabilized after two weeks.
Mary Vaughan –
Great for small ponds too. I added it directly to my pond filter and saw a noticeable drop in nitrite levels. Easy to maintain and doesn’t clog easily.
Irene Miller –
Works well with my wet/dry filter. The media stays intact even after several water changes. No fish stress reported, and water quality has improved steadily.
