This RO Water Filter System is an excellent Pre-Assembled Reverse Osmosis System to eliminate impurities found in city water. This machine requires minimal space. Installation takes only 5 minutes! Ideal for Aquarium Water Treatments like Fish Tank's, Reef Tanks, Saltwater & Freshwater Aquariums; also for laboratory testing, and other applications where ultra-pure water is necessary. Optimal aquarium filters for fish, coral, turtle aquarium's & other aquatic life, live rock, salt rock & plants. SPECIFICATIONS: Removes up to 99% contaminants. Air-leak tested, leak-free fittings & long lasting fish tank filter's ensure durability & mitigate chances for damage & breakage. Filtration Stages: 5 Micron Polypropylene Sediment-> UDF Activated Carbon-> Coconut Carbon-> 150 GPD RO Membrane-> DI Cartridge x 2. Garden Hose is included with tubing & connections. RO Membrane is flushed & pre-installed in the membrane housing. Gauge notifies when to replace filters & indicates water pressure levels. 0 TDS PROMISE: Highest Caliber Nuclear Grade Dual Deionization provides optimal performance for the membrane. The higher the rejection rate of the membrane the longer the DI will last. Many customers use dechlorinators which are designed to neutralize the chlorine in the water but this removes no harmful contaminants from the water. Whereas DI polishes off the remaining TDS of the membrane, leaving fewer TDS out of the membrane making the DI last longer & perform better certifying 0 TDS water. SPECIAL ACCESSORIES: Manual Flush Valve, pre-installed with flow restrictor to save you the time & hassle, makes this water dispenser superior to any other by increasing the life of the unit, reducing possible leaks & saves you valuable time when flushing the system. Each easy-to-read two-tone PSI Gauge printed in bold UV resistant ink is tested for accuracy & leakage. Our TDS Meter is designed for demanding applications like oil refining, chemical, food processing, water purification & more! Fully loaded RO/DI system with eletricaly booster pump for low water pressure areas, HM digital tds meter, and pressure gauge. The ultimate filtration system for reef tanks, salt water/fresh water aquarium's & other applications where ultra-pure water is necessary. Install in minutes. Even if your water pressure is low the system will make sure the flow stays at an optimal level. The pressure gauge makes it easy to tell when the filters need to be replaced and water pressure levels for supreme water filter performance at all times. 150 Gallons per day water filtration capacity. Built in California using foreign and domestic parts. HM Digital TDS meter helps monitor the water quality ensuring 0 TDS water at all times. Removes up to 99% contaminants for safe 0 TDS/PPM water. This is the ultimate RO/DI system. Comes with a flush kit.
