The AquaRO50 is an essential, complete reverse osmosis system to protect and purify water for use in aquariums. Designed to produce a continuous supply of high quality water, the AQUARO is the perfect system for tank top-up applications procing up to 200 litres per day of on-demand purified water. Working on mains pressure (2.8 bar+) and requiring no pump or electricity the system takes up very little space and can be easily mounted horizontally or vertically for convenience.
