LiquaGen 5 Stage RO/DI Aquarium Reef Water Filter System 150 GPD – Reverse Osmosis Deionization Unit for Saltwater Marine Coral Fish Tank – TDS Meter & Pressure Gauge Included

???? PURE WATER FOR MULTIPLE APPLICATIONS – Ideal for reef aquariums, saltwater tanks, freshwater systems, hydroponics, humidifiers, lab use, and any setup requiring ZERO TDS water. Take control of your source water from day one with a complete 5 stage RO/DI filtration system designed for performance and reliability.

???? TRUE 5 STAGE 150 GPD RO/DI SYSTEM – Fully loaded filtration stack includes 5 micron sediment filter, UDF carbon, carbon block, high rejection reverse osmosis membrane, and mixed bed color-changing DI resin for maximum performance.

???? HIGH REJECTION RO MEMBRANE – Premium 150 GPD spiral-wound RO membrane engineered for strong dissolved solids reduction under proper PSI and temperature conditions. Designed for steady production and dependable aquarium water preparation.

???? COLOR CHANGING DI RESIN – Mixed bed deionization cartridge provides final polishing stage after RO filtration. Resin changes color as it exhausts, giving a clear visual indicator so you know exactly when it’s time for replacement.

???? DUAL INLINE TDS METER INCLUDED – Monitor membrane performance and DI output separately. Dual probes allow you to track system efficiency in real time and stay ahead of filter maintenance without guesswork.

?? GLYCERIN FILLED PRESSURE GAUGE – Durable pressure gauge helps monitor incoming PSI and signals when pre-filters may need replacement. Glycerin filling reduces vibration for improved accuracy and longer gauge life.

???? MANUAL FLUSH VALVE BUILT IN – Integrated flush valve helps rinse the RO membrane during startup and routine maintenance. Supports membrane longevity and stable system performance over time.

???? AUTO SHUT OFF & CHECK VALVE – Built-in auto shut off valve and check valve allow use with float valves or storage tanks for controlled operation and reduced water waste during production cycles.

???? PRE-ASSEMBLED FRAME UNIT – Compact single frame design ships mostly assembled with minor setup required. Connect tubing and fittings, hook up to a water source, and be operational in minutes.

???? EASY INSTALL & LOW MAINTENANCE – Designed for simple setup and straightforward filter changes. Flush kit, accessible housings, and clear layout make ongoing maintenance fast and manageable.
