Rena NEXX External Filter

The Rena NEXX is the latest in aquarium filtration technology. Designed for use in freshwater and saltwater aquariums, it is the only external filter you will ever need to buy. The NEXX unit can process up to 500 l/h and is suitable for aquariums up to 200 litres. For larger aquariums, NEXX expansion kits can be added to increase the capacity to 400 or even 600 litres. There is no need to buy a whole new filter. With chemical and biological filtration as well as a 'no bypass' system to ensure 100% of the water passes through the media, it is amazingly efficient. Featuring an in-built quick-shut-off system, the NEXX can be cleaned and maintained in mere minutes without even turning it off! The autostart system means there is no need to prime the filter and no water spillage! This incredibly light and durable filter comes with a 3 year guarantee.
