Aquario Neo Filter Media - The newest generation of the biological filtration mediums
October 02, 2021
The 3 types of the Neo biological filter media from Aquario have just been presented as the latest line of the Korean manufacturer’s product range. According to Aquario, they are the result of 5 years of ongoing research and development, and they claim that they have become the first company in the world to create a biological filter media with a functional surface area of 3200 nm per liter. This has been achieved by creating pores with a larger diameter, which will permeate the core of the material, allowing water to flow through it. The slow flow favors the beneficial bacteria living in the smaller pores, allowing them to do their valuable work comfortably.
The manufacturer uses a spectacular video to show how many pores are available for bacteria inside the media, in contrast with other reputable manufacturers' high-quality products.
What can we conclude from the video? For example, the material will sink immediately when submersed, suggesting that water passes easily through the larger pores. And the "pearling” that lasts for minutes shows that air can escape relatively fast from the smaller pores – it is not trapped there – and can be replaced by water easily. This in itself is commendable indeed. Aquario could have sat back and said here's a first-class filter media buy one, take one.
However, this company is renowned for serious innovation, so they didn't stop there. Further developments have resulted in three different types of filter media that influence water parameters in different ways.
This is perhaps the most exciting of the three, as the filter media can shift the aquarium water parameters toward a slightly acidic direction. The test video below shows the result.
Slightly acidic water is very beneficial for planted aquariums! It is favored by freshwater shrimp and South American and Southeast Asian fish. In case of hard tap water (like in Hungary for example), using the Aquario Neo Media Soft can be an effective solution to reduce the pH of the slightly alkaline water. In addition, only ADA Bio Rio G has been able to deliver a similar miracle in the filter media market so far. However, the Neo has a larger surface area and is a more structured material, so there is no need to worry about clogging the filter.
As the name suggests, this media is totally neutral, which can be an important factor if you don't want to alter the pH of the water. For example, if you are using soft water and have a CO2 system (that reduces the pH), this filter media will perform better than Neo Media Soft. In this case you can even choose the grain size. The “M” size is usually good for most filters, but consider using the “L” size for filter systems with a higher biological load.
Aquario Neo Media Hard
This filter media is designed explicitly for alkaline environments if our aim is to keep this kind of higher pH. This is the case for tanks inhabited by cichlids from Lake Tanganyika, Lake Malawi, or Lake Victoria; and it could also be the case of saltwater aquariums. As most biological filter media are also slightly alkaline, it is here that their large surface area (3200 nm/liter) makes them stand out from their competitors. It is also important to note that the product is 100% natural, and only thermal energy is used in its production.
How does the Neo Media do its biological filtering work? The manufacturer has carried out the following experiment.
They added Ammonia (5ppm) to the cycled (4-weeks old) Neo Media filter media, and they re-tested the Ammonia level every 2 hours. The result was that within a few hours, the bacteria working in the filter media had completely processed the Ammonia and even the resulting Nitrite. A spectacular result, although I would have appreciated to see the numbers for some competing filter media alongside these data. ;)
To sum up, Aquario has created a filter material worthy of its brand reputation, which will cause its competitors some real headache in the future. To end on a high note, Aquario, with the Neo Media filter media range, has stirred the pot... :)
