Product Features

Complete System

Includes pre-assembled system with filters, garden hose adapter (other options available), color coded tubing, and installation/maintenance manual.

NSF Certified Components

All components, including the filters and membrane, are NSF certified for the highest quality system.

5-stage Filtration

Stage 1 - 1 micron sediment filter removes particulates
Stage 2 - 1 micron carbon block filter removes chlorine, tastes, chemicals, and odors not caught by the GAC filter
Stage 3 - 100 GPD high silicate removal TFC reverse osmosis membrane, purifies the water removing 90-95% of contaminates
Stage 4 - Mixed Bed De-ionization filter - removes remaining contaminates, providing 99.9% effective contaminate removal
Stage 5 - Inline De-ionization filter - Second DI filter ensures the highest purity while providing longer filter life

2 Connection Options

Your choice of connection options for quick and easy setup
Garden Hose Connector - Simple connector fits standard garden hose thread
Diverter Valve - Connection to most standard faucets with valve to direct water to system

Easy Installation

Color coded tubing and detailed make installation simple!

Flushing Flow Restrictor

Regulates waste water, providing proper pressure against the membrane to ensure high efficiency. Flushing valve allows for additional membrane flushing for extended membrane life.

Check Valve

Prevents tank from pushing water back through the membrane and down the drain, reducing waste.

Clear Sediment Filter Housing

The housing for the sediment filter is clear, which helps you to monitor the condition of your sediment filter which may indicate when it needs changed

Mounting Bracket

Allows for mounting of the RO system, increasing your installation options

High Quality Standard Size Filters

High quality NSF certified filters in standard 2.5-inchx9.75-inch size. Compatible size filters are readily available at most hardware and aquarium stores

100GPD High Silicate Membrane

We use 100 GPD high quality, high silicate removal membranes in our RO systems


Product Description

Paying for distilled water can get expensive, not to mention the hassle of transporting it or running out. If you own a Reef aquarium or use ultra pure water for any other reason, this system will save you time and money by allowing you to make distilled quality water when you need it!

The Reverse Osmosis (RO) membrane removes 95-97% of water contaminates, providing high quality water and doing most of the purification. The DI (de-ionization) filter removes 99% of contaminates, and when coupled with RO, provides 99.9% effective contaminate removal. The second inline DI filter ensure the highest purity water and extends filter life. The DI filter uses a resin to remove contaminates, and as time goes by the resin becomes exhausted. Eventually enough of the resin will be exhausted that full filtration no longer occurs, and at this point the DI filter is usually changed, even though some removal capacity still remains. With a second DI filter the first DI filter can be completely exhausted before replacement, resulting in less frequent filter changes.

Since the membrane provides long lasting purification, and the DI filter provides high purity filtration, coupling the two treatment processes together allows for lower filter cost than DI only systems and higher purification that RO only systems

Our systems are quality made in the USA using NSF certified components, so high quality is assured. Top that off with a 30 day satisfaction guarantee and a 1 year warranty and you get one of the best systems available! Plus we offer phone and email support to answer any questions you may have, so you can feel confident in your purchase.

    RO/DI Psarion PSI Reef system

    System was very satisfactory except for missing connectors for proper hookup, fortunately I had connectors from my previous system. Other than that it works great!

    Great system! Works well just lacks enough connectors, had to use connectors I had from old system but had it up and running in about half an hour. Also good support from the company on any problems a big plus!
