Maxspect Nano-Tech Bio-Media

Over the last few years there has been a trend on aquariums that have a high volume of corals and fish but also keeping rock and landscaping to a minimum.  The use of negative space makes such tanks absolutely stunning by bringing emphasis on the colorful corals and fish rather than walls or mountains of rock.

In order to maintain such systems without compromising filtration, hobbyists have resorted to adding rubble or rocks to their sumps.  Unfortunately, this method requires lots of space, which is something most of us do not have. 

To remedy this ongoing issue, Maxspect has released their brand-new Nano-Tech Bio-Media made from 100% ceramic beads that are completely inert.  This means no leaching any elements into the tank at all even after prolonged use!

Maxspect Nano-Tech Bio-Media comes in two different shapes to suit all needs. 

The Maxspect Bio-Spheres are made up of around 220000 very small ceramic beads, and each bead has over 2.4 square centimeters of surface area.

The Bio-Spheres come in two different options.  A 2-lbs box containing 44 biospheres with a total surface area of over 25000 square feet, and a 4-lbs box containing 88 Bio-Spheres with a total surface area of over 51000 square feet! 

To put this into perspective, the White House has a total space of 55000 square feet… that we know of. 

Maxspect Bio-Media is also available in blocks.  One box of Maxspect Bio-Blocks contains two separate blocks measuring 4 by 4 by 1 inch.  One Bio-Block is made up of around 3.5 million beads with a total surface area of just over 11000 square feet.  One box with two Bio-Blocks has a total surface area of over 23000 square feet.  That is almost half a football field!!!

That is a LOT of surface area for bacteria to colonize!!!!

Basically, the media is built by packing lots of beads together in a tight formation where there is only a single point of contact between each bead, allowing water to flow through the entire media without much resistance.

Now, I know some of you are probably thinking that this is nothing new and that other companies out there have similar products.  Well, the Maxspect Nano-Tech Bio-Media is based on filtration technology called Biological Aerated Filter or (W-BAF) commonly used by the sewage treatment industry. I think it is safe to assume they know what they are doing!

The main difference is that due to scalability, sewage treatment plants do not use spheres or blocks but instead, they use a sand bed technique.  Maxspect has taken this filtration a step further and using proprietary and patented technology, created spheres and blocks which are more feasible to use in our hobby.

At first, Maxspect created this product for public aquariums but after seeing how efficient it was at treating large exhibits they have made it available to us, hobbyists.

So, how much media should I use in my system?  Basically, a 2 lbs box of Maxspect Bio-Spheres can treat up to 750 gallons of water and a 4 lbs box can treat 1500 gallons.   A single block of Maxspect Bio-Block can treat about 375 gallons of water.

For best filtration performance and maximum bacterial colonization, add the media to high-flow areas of your sump or media reactor.


When it comes to simplicity, Auto Aqua does it best. It is amazing that these simple outlets can help safeguard our aquatic investment and beloved pets.
