There are three main types of filtration. These are known as Mechanical, Chemical and Biological.
The sponge part of your filter is the mechanical filtration and basically works like a sieve. Fish waste sinks and gets drawn into the filter sponge where it is trapped. When you change your filter cartridge you remove all this waste in one go.
In the bottom of your filter cartridge under the sponge are chemically active filter media. These remove specific substances and adjust the hardness a pH levels of your water. Typically, these chemicals lose their effectiveness after about four to six weeks.
It’s Mother Nature doing what she does best. Biological filtration happens in your Ceramic Media and needs three things to thrive; fish waste, oxygen and time.
First a little bit about Ceramic Media. It’s made from clay that’s fired to 1500°C. This makes it knobbly and under a microscope you’d see a honeycomb structure. If you could flatten out the surface area of your Ceramic Media you’d cover a football pitch.
All this surface area slowly gets populated with beneficial bacteria. You can’t see it, but this tiny bacteria neutralises ammonia and nitrite in your aquarium. Over time this bacteria thrives. Generally speaking the more established your aquarium gets, the easier it is to look after.
The great thing about a biOrb is that the biological filtration need never be disturbed. You can remove the chemical and mechanical filtration (in the cartridge) and replenish them without upsetting Mother Nature’s beneficial bacteria in your Ceramic Media.
The biOrb filtration system explaIned
- Air driven filtration system creates vigorous water flow and a constantly changing water surface. This maintains oxygen saturation.
- The circular flow of water then collects any fish waste on its way down.
- It draws the waste through the ceramic media where the natural biological filtration absorbs some toxins. The freshly oxygenated water also feeds the bacteria.
- Any remaining waste is trapped in the sponge cartridge. The water then passes through resin particles and natural stabilisers to remove toxic substances and keep the pH levels constant.
- The clean water is then oxygenated as it flows back up the bubble tube to repeat the cycle.
