Seachem Matrix Bio Media
The Seachem Matrix Bio Media is just one of those products that is known to work. It is without a doubt one of the highest surface area filter medias out there. The Seachem Matrix is an extremely high porous inorganic solid around 10mm in diameter. Despite being small, each liter of Seachem Matrix yields the surface area of 170 liters of ping pong balls or 700 square meters.
Another selling point is that it is completely inert and doesn’t break down, so they don’t need to be replaced. The direct result of all of this is a crazy good control of ammonia, nitrite, nitrate and a completely clean tank without having to do any work.
Seachem takes great pride in their product and the sound engineering behind it. In fact, they are so annoyed at companies like Eheim Substrat Pro and JBL MicroMec for artificially boosting their surface area measurements that they decided to do an official study on this subject. Their findings are of course that any way you measure, the Seachem Matrix Bio Media is clearly the winner by at least 10 fold.
Regardless of the technicalities, we had to see and test for ourselves as well as poll users. This stuff is leagues above any filter we have ever used, including those cheap ceramic rings. The Matrix clears your aquarium in no time and works for longer than most competitors. And as a cherry on top, it is priced cheaper than most products out there. This is without a doubt the best biological filter media for the value.
CerMedia Marine Pure Block Bio Filter Media
It should be no surprise that the CerMedia Marine Pure Block is one of our top recommendations. Although this biofilter media block is quite pricy, it is the best biological media filter in terms of ammonia, nitrite, and nitrate removal. This unit is designed to provide deep anaerobic zones that allow for the removal of nitrates in passive systems. We would recommend you use it in sumps or in extra large filters.
The selling point of the CerMedia Marine Pure Block is that it can substitute for a live rock in a reef tank and look more natural. Furthermore, it can improve upon deep sand beds or live rock. It also helps reduce nitrates more efficiently without harming the environment too much.
This biological filter block has a huge surface area and an open flow porosity. Keep in mind that you have to give it a proper rinse under tap water to remove loose particles and remove chlorine. IN terms of performance and keeping your tank clean, this thing is a beast. It can take care of a 200 gallon reef tank no problem. Additionally, you can just leave it in there for a year or so without replacing it or rinsing it again.

Also they offer more capacity than its competitors and present a great environment for beneficial bacteria to grow. Like with most biological filter media, they help reduce ammonia and nitrite.

The Eheim Substrat Pro is great for fresh and marine water. Many users like it because they can easily be rinsed, cleaned, and reused. You can do this every 1 to 3 months. These beads can reduce peak nitrite loads, which allows you to maintain the biological filter media less often. You can replace these beads every 3 to 6 months. Overall, the Eheim Substrate Pro has a great open structure for water penetration and bacterial colonization. It performs very well and is priced very reasonably.
