Creating a successful reef tank requires hard work, dedication, and passion. The foundation of any great reef tank (small or large) is the quality of water you provide to your fish and corals. The first step to having a thriving aquarium is choosing the right RO/DI system.
Our city and well waters have a number of harmful contaminants like chlorine, chloramine, lead, arsenic, and others. Many times it's not fit for drinking, let alone the perfect 0 TDS water needed. Many customers use dechlorinators which are designed to neutralize the chlorine in the water and is one of the worst ways to attempt to purify the water. They remove no harmful contaminants from the water. Many customers like to purchase water from the local fish store but that can become expensive in the long run.
Here at LiquaGen, we offer a wide variety of aquarium filter for both small and large tanks. As a company, we believe in providing affordable, high performance water technology where you can make as much pure water as you need whenever you need it. We have a wide variety of reverse osmosis systems designed specifically to your needs and wants.

Choosing the best RO/DI system for your needs:
The main difference between RO/DI's are:

• The number of filtration stages and the number of gallons a system can make a day (GPD - Gallons per day). More GDP means more water.
• Add on features which enhance the performance and accuracy like pressure gauges and TDS meters. This is something a reefer will add at one point or another to monitor proper performance of the unit and keep the fish healthy.
• City water versus well water applications - Well water units require more filtration stages as the water is untreated compared to city water filtration which is pre-treated by the cities.

Standard Benefits of LiquaGen RO/DI systems:

• Manual Flush Kit - All LiquaGen products come with the manual flush kit as standard, it makes it a lot easier to flush the unit, therefore increasing the life and performance of the membrane.
• Pre-assembled - All our RO/DI units are pre-assembled and tested in our factory, simply attach the tubing and you're good to go!
• Warranty - All our RO/DI units have a lifetime warranty
• Filtration Quality - We used the best OEMs in the market like GE to provide the highest quality of filtration with filters which are built to last.
