Bubbles:- Bubbles are created by the air pump. The air pump forces air through the base of the aquarium creating air bubbles which rise up through the bubble tube. When the bubbles hit the surface, oxygen is released into the water. Surface agitation also allows carbon dioxide to escape out of the water.
The sponge and fine mesh:- These provide mechanical filtration, working like a waste bin, by trapping solid particles of waste and debris keeping them out of the water.
Activated carbon and resins:- These provide chemical filtration by absorbing some nitrate, phosphate and other chemicals from the water.
Cermaic media:- The rocks at the base of the biOrb provide an ideal home for filter bacteria to live, multiply and work.
Unlike many traditional aquariums, ceramic media is used for effective biological filtration. Ceramic media provides a massive home for filter bacteria.
Filtration cycle:- Fish eat food, the waste produced by the fish (ammonia) is consumed by the filter bacteria and turned into less harmful pollutants like nitrate. Some of these pollutants are absorbed by active chemicals in the filter cartridge and eaten by plants. The rest must be diluted with regular partial water changes.
The more fish food or fish that enter the aquarium, the more pollutants are produced as a result. If these pollutants build up they will encourage green water and poor fish health.
Mechanical and chemical filtration is housed in the easy to change filter cartridge.
This significantly reduces maintenance whilst helping the water remain healthy and crystal clear for up to 8 weeks between simple filter cartridge changes.
Please note that regular filter cartridge changes will increase the efficiency of the filter system.
