• NEW AND IMPROVED Ultra-Efficient Dry Membrane
• Reduces 95%+ of total dissolved solids (TDS)
• 20% Increased Flow Rate
• Filters 600+ gallons per day (GPD)
• Replace between 6 months–2 years

Flow rates of RO systems are based on source water @ 65 psi / 77° / 500 ppm

RO output depends on the source water temperature. At 77°, the system should produce 100% of the rated output. As the temperature drops or increases, so does the output

Our best-selling High-Flow system just got better! Improved Dry Membrane design now with 20% increase in flow rate. Up to 1,200+ GPD!

• Capable of producing more than 1,200 GPD (gallons per day) or 50+ GPH (gallons per hour) of pure water, perfect for medium to large hydroponic operations (Flow rates of RO systems are based on source water @ 65 psi/77°/500 ppm)
• Highest flow rates and the most efficient system in the industry!
• Lowers parts per million (ppm) of total dissolved solids (TDS) by 95%+
• SAVE MORE WATER by running a 1:1 waste to product water ratio
• Includes ChloraShield™ carbon filter for 100% chloramine removal

• 98+% PPM Rejection
• 1 membrane for stealth-RO150 and 2 membranes for the stealth-RO300
• Filters up to 150 GPD (gallons per day)
• Replace between 6 months to 2 years

THERE ARE TWO INDICATIONS AS TO WHEN TO CHANGE YOUR MEMBRANES

1. Test the RO and source/inlet water to see what percentage of the inlet water’s PPM the Stealth-RO150 is filtering out (rejection %). You should see approximately 98% of the inlet PPMs being removed when the membrane is new. If the rejection % falls under an acceptable level (typically 90%) it’s time to change the membrane
2. When the flow rate of the product water slows down significantly. This can also happen if your pre-filters are clogged. If you change your pre-filters and the product water still flows slowly then it’s an indication you need a new membrane. When it doubt contact HydroLogic

• This Float Valve features a ½" Barbed Fitting and adjustable water level
• It can be mounted vertically or horizontally
• Stainless Steel and PVC Components
• The float valve allows you to fill a reservoir or tank, unattended, to your desired water level
• Never flood your garden again!

These custom, poly-injection formed, ebb & flow fittings are designed to be used with feed and drain watering systems. Outlets are available in 1/2" (13 mm), 3/4" (19 mm) and 1" (25 mm) openings. Optional multi-level, overflow extensions and debris screens are available and easily installed into the outlets.

These fittings require a 1-3/8" (35 mm) hole to be drilled in your flood tray. After inserting the 1/2" Bulkhead Fitting into the tray, use 1/2" tubing to connect to your water pump. Install the 3/4" Bulkhead Fitting in the tray and attach the Bulkhead Extensions to maintain the desired water level in the flood tray while the water pump is running. Attach the Bulkhead Screens to the top of both fittings to prevent debris from entering the reservoir and to prevent water from shooting out and splashing when the pump is on.

This screen attaches to the Botanicare Barbed Fitting to deep debris from the grow tray from ending up back in your reservoir.

1-5/16" extensions for the Botanicare Barbed Fittings. Use these to increase the height of the flood cycle.
