HydroLogic Stealth-RO150 Reverse Osmosis System - 150 GPD

Low-TDS Water for Hydroponic Reservoirs - Up to 150 Gallons Per Day

Tap water with high dissolved solids limits how precisely you can control a nutrient solution. This reverse osmosis system filters source water through a sediment filter, a carbon filter and RO membranes, and it lowers total dissolved solids by up to 98%. You then build your nutrient mix from a clean, consistent base.

Rated for up to 150 gallons per day, this unit suits indoor growers and small commercial rooms that refill reservoirs regularly. It is sold as a single system and arrives with filters, membranes, tubing and tools.

Key Features & Benefits

• Up to 150 GPD production — supplies enough water for regular reservoir top-offs and refills.
• Up to 98% TDS reduction — gives you a low-ppm starting point for nutrient mixing.
• 1:1 and 2:1 flow restrictors — let you pick the wastewater ratio that fits your water use.
• Two RO membranes and a power flush kit — help you maintain membrane performance.
• Tubing and wrench included — lets you plumb the unit in and service the housings.

Who Should Use HydroLogic Stealth-RO150

Hydroponic growers who mix their own nutrient solutions and want tighter control over water quality will get the most from this system. It also fits growers with a steady daily water demand.

Frequently Asked Questions

Q: What inlet pressure does it need?
A: The system operates with inlet pressure between 40 and 80 psi. Do not install it where pressure exceeds 80 psi or where water hammer is a problem.

Q: What does the 150 GPD rating depend on?
A: Output ratings are based on source water at 65 psi, 77°F and 500 ppm. Colder water, lower pressure or higher ppm will change real-world output.

Q: What is TDS?
A: TDS means total dissolved solids, the minerals and salts dissolved in water, usually measured in ppm. Reverse osmosis membranes remove most of them.

Q: What is the difference between 1:1 and 2:1 ratios?
A: The ratio compares wastewater to product water. The included flow restrictors let you choose the setting that suits your water-use goals.

Q: How often should I replace the housings?
A: Replace the housings every 3 years. Filter cartridges and membranes follow their own replacement schedules in the filter guide.

Q: Which tubing is included?
A: The kit includes 5 ft of white inlet tubing, 8 ft of blue product tubing and 8 ft of black wastewater tubing.
