Merlin Garden Pro RO system 

A reverse osmosis system that gives continuous water flow without a pump or storage tank? The Merlin Garden Pro high-flow reverse osmosis system does just that! 

This ingenious RO unit operates on water line pressure, which eliminates the need for an electrical pump in most applications. And it reduces impurities in 30 gallons per hour - that's 750 gallons of water per day!

Hydro-Logic's Merlin Garden Pro Reverse Osmosis system has a 4-stage design that uses a carbon pre-filter, two RO membrane elements, and a carbon post-filter to produce the highest quality hydroponics gardening water. It's compact design sits nicely under your sink, or by your reservoir.

Merlin Garden Pro reduces 95%+ of water impurities, including calcium, chlorine, magnesium, iron and other contaminants.

The Merlin Garden Pro RO system is engineered to have less than half the number of connection points so there's less chance of leaks. Quick-latch snaps into place and locks down all four tubing connectors in one easy step. And it never runs dry!

It carries the Water Quality Association Gold Seal and is NSF/ANSI 58 Certified. Comes with complete product literature and training support and carries a 3-year residential warranty.
