There is a large range of filter media on the market and choosing the right ones for your filter can be a little challenging. In general, most internal filters use sponge or foam pads to filter the water. Hang-on and external canister filters usually use a mix of mechanical, chemical and biological filter media.
Depending on your filter type it is best to fit as much fish tank filter media into your filter as possible to maximise your filter’s capacity and effectiveness.
There are three different types of aquarium filter media used to filter the water.
This is usually the first stage of most filters. They include ceramic noodles & rings, foam and filter sponges. This type of mechanical filter media generally traps larger particles and debris. Other types of filter media, such as filter wool and fine filter pads, are used to trap smaller debris and finer particles to help polish the water.
Aquarium bio filter media helps break down ammonia, nitrates, and other harmful substances in the water. This type of aquarium filtration media is usually porous and has a high surface area allowing lots of nitrifying bacteria to colonise and settle within the filter media. Some of the best aquarium bio filter media include Seachem Matrix and Eheim Substrat Pro. If you’re looking for something that’s great value, you can’t go past the Aqua One ceramic substrate line CeramiSub and PremiumSub.
Chemical filtration media absorb impurities such as colours, odours, medicines and other contaminants in the water. These include activated carbon, such as the Aqua One filter media range ChemiCarb and PremiumCarb. There are also chemical filter media targeted to absorb toxins such as ammonia, nitrates and phosphates.
Seachem Purigen is a very popular and effective absorbing resin that removes tannins, the yellow colour leached by driftwood, helping your water to stay crystal clear.
