The Ocellaris range from Aqua One is a user-friendly range of external pressurised filters. Their modular filter basket layout allows you to customise your filter media in a way that best suits the needs of your aquarium, and the baskets lift in and out easily for maintenance.
They come supplied with all the filter media and pipework that you need to get started, making these filters a plug-and-play solution. They are easily primed using the priming pump installed in the main pump head, making the set-up process simple and fast.
This range of filters are highly energy efficient, powerful, and run extremely quietly, making them a great choice for a wide range of home aquariums. It also comes with a quick release tap system, making water changes and maintenance a breeze.
