Commercial & Bulk Purchasing
We support operations & licensed facilities with volume pricing, dedicated account managers, and custom equipment consultation.
- You are investing in a dedicated filtration unit because your tap water TDS levels fluctuate enough to lock out essential nutrients
- You are clearing up space in your garden because your current commercial-grade system is too bulky for your room footprint
- The included membrane flush kit is the real value here because it keeps the RO filter from scaling up prematurely
- We recommend the 1:1 waste ratio setting if your local water pressure stays consistent throughout the day
- Growers who switch from unfiltered tap water say they finally stopped seeing those stubborn mineral spots on leaf surfaces
- Users with limited room capacity say this unit gives them the same high-purity water as larger systems without the clutter
HydroLogic Stealth-RO150 150GPD Reverse Osmosis System
Smaller hydroponic gardens still need reliably clean water — just without the footprint or output of a commercial-scale unit like the Evolution-RO1000. The HydroLogic Stealth-RO150 is built for exactly that gap, producing up to 150 GPD of ultra-pure, low-PPM water for gardens that don't need a high-capacity system but won't compromise on water quality. For even more compact needs, some growers opt for the MicRO 75GPD system for portable applications.
The Stealth-RO150 lowers total dissolved solids (TDS) by up to 98%, giving growers a clean, consistent baseline for nutrient programs. It's also engineered for efficiency, delivering 50% water savings over similar reverse osmosis systems with a choice of 1:1 or 2:1 waste ratios. If your water demands increase, the Stealth-RO300 offers a similar design with double the daily output. A included Membrane Power Flush Kit helps maintain membrane performance over time, extending the system's usable life between replacements.
Compact at just 18.5" x 16" x 6" and 10.8 lbs, the Stealth-RO150 fits easily into tight grow spaces while still delivering commercial-grade filtration performance at a smaller scale.

Frequently Asked Questions
How much water does the Stealth-RO150 produce?
The Stealth-RO150 produces up to 150 gallons per day of ultra-pure, low-PPM reverse osmosis water under standard test conditions (65 psi, 77°F source water, 500 ppm).
What if I only need to remove chlorine and sediment?
If you don't require TDS reduction, a system like the smallBoy Dechlorinator & Sediment System provides high-flow filtration without the waste water of RO.
Can I adjust how much water the system wastes?
Yes — it comes with both 1:1 and 2:1 ratio flow restrictors, so you can choose the setting that fits your priorities between speed and water conservation.
What's included for ongoing membrane maintenance?
The system ships with a Membrane Power Flush Kit, which helps maintain membrane performance and extend usable life between replacements.
What tubing and fittings are included for installation?
The Stealth-RO150 includes 8' of 3/4" white inlet tubing, 8' of 1/4" drain tubing, 5' of 1/4" product water tubing, and a 1/4" QC ball valve inline shut-off for a complete setup.
How often do the filter housings need replacing?
HydroLogic recommends replacing the housings every 3 years to maintain consistent filtration performance.
Is this system a good fit for smaller hydroponic gardens?
Yes — at 18.5" x 16" x 6" and 10.8 lbs, the Stealth-RO150 has a compact footprint tailored to hydroponic gardens that need up to 150 GPD without the size of a commercial-scale system.
