## Overview

The RO/DI 150GPD Reverse Osmosis Dual DI Aquarium/Reef System is a six-stage filtration unit featuring a 150 gallons per day membrane and dual refillable color-changing DI cartridges. Designed and manufactured in the USA, it ensures ultra-low Total Dissolved Solids (TDS) for optimal aquarium and reef water quality. Its clear housings provide easy visual monitoring, while the dual DI setup maximizes resin usage and reduces operating costs, making it a cost-effective, high-performance solution for professional aquarists.

## Description

Six Stage RO/DI Aquarium System. 150 GPD Membrane. Dual DI REFILLABLE Color Changing Media Cartridges. ALL CLEAR HOUSINGS. Reverse Osmosis systems, combined with A DI after filter, will give you the lowest TDS reading for your aquarium water supply. DI Resin is necessary to reduce Total Dissolved Solids (TDS) to zero and is the last stage of an RO/DI unit. It is unnecessary to use the expensive proprietary DI cartridges that other RO manufacturers sell. Simply buy a refillable DI cartridge and fill with DI resin. You'll save money and get the same results. A constant supply of high purity water can be obtained by using two cartridges in series and allowing the first cartridge to completely depleted. During this operation, the second cartridge ensures that the water leaving the system is of the highest purity. New cartridges are placed into the polishing position and the remaining cartridge is put into the “roughing” position. This ensures complete utilization of all the exchange capacity, which lowers operating costs while increasing average quality.The clear cartridges are refillable, so you can save with buying media in bulk, and using the inline cartridges again, and again.

Review: Made in the United States - It’s bassackwards. In from the right out of the left. Are they sure it has a 150 gallon RO membrane? My other two from a reputable company have one membrane for 75 gph and 2 membranes for 150 gph. Very easy install with provided instructions. Working perfectly even without a water pressure booster. I’m at 40 psi. Adding booster will give you at least 80 psi.
Review: Still a bargain compared to the "Saltwater specific recommended ones" - Long term user.... I bought my unit in 2019, I did add a booster pump with gauge and another membrane simply to be more efficient. never has it given me a problem and i Highly recommend it.. crazy at the price changes of our time in 2019 when I bought it it was $169

### ⭐⭐⭐⭐ Good system.
*by J***Y on April 19, 2022*

It is a great starter system - especially if you are doing aquariums. Much cheaper than some comparable systems with exact same amount of stages. Only recommendation I have is change the DI resin if you want 0TDS. RO is producing 3ppm and I was not getting 0 output until I swapped out the resin. Not a big deal, it’s a disposable item of a system anyways. I make roughly 200 gallons/month with this unit. My water pressure is horrible where I live and get about 50 gallons in 32 hours.
