Perfect for professional aquarists seeking superior filtration performance and ecosystem balance. ## Description Product description Nano-Tech Bio Blocks are carefully manufactured to ensure optimal quality and porous structure and thus effectively control the quality and stability of the water column. Each unit of I Nano-Tech Bio Block has an area of 1.080 m² (11.635 ft²) for the creation of bacterial colonies. Nano-Tech Bio Blocks are excellent for creating bacterial colonies in the form of bio-nano mixed-structure films. They allow different species of bacteria and fungi, such as nitrifying bacteria, yeast, phototrophic prokaryotes, etc. to grow on their large surface. Maxspect Nano-Tech Bio-Media are made from 100% small ceramic beads and are completely inert. Each of the bio spheres is made up of over 220,000 of these small ceramic beads and each bead has a surface area of 1.25cm2, which in turn means that each block has an area of over 1,080 m² (11,635 sq.ft). The structure of our bio block essentially consists of putting lots of beads together in a tight form; there is only a single point of contact between each ball and the other so the water can easily flow through the entire bio block. This technology has been used in the wastewater treatment industry for a very long time. This wastewater treatment technology is called aerated biological filter (W-BAF). However in the treatment of wastewater these balls or blocks are not used, we use the sand bed technique which is not very feasible in our aquariums so Maxspect produced these bio balls and bio blocks of pearls using patented technology. Directions Can be used directly in the tub, sump, external filters, waterfalls, etc. and is excellent for creating bacterial colonies in the form of bio-nano mixed-structure films. Review: Great filtration product - Appears to be doing a fabulous job of keeping the phosphates and nitrates in check. I'm finding they work best either in a filter cup or raised on egg crate near to a consistent flow (mine is near to the skimmer) Review: Arrived on the following day - First time use it. It’s hard to cut for the right size. But on the review this is the best bio block ## Features - MAXSPECT NANO TECH BIO BLOCK 2 PCS BIO BALLS FOR EXTERNAL FILTER, SUMP AQUARIUM FRESH AND MARINE - Stabilised microbial wastewater treatment technology with biological aerated filter (W-BAF).
