Growonix GX200-HF Reverse Osmosis Filter - 200 GPD - 14 x 7 x 16-in - 1 Membrane

Compact 200 GPD Water Filtration for Hydroponic Reservoirs - 14 x 7 x 16 in

Feed water with high dissolved solids makes nutrient mixes hard to control. This reverse osmosis filter uses one high flow polyamide membrane to reduce dissolved solids and rated at 200 gallons per day of permeate, so you start each reservoir from cleaner water. Nominal salt rejection is 96%.

At 14 x 7 x 16 in and 15 lb shipping weight, this single-unit system suits hobbyists and regular indoor growers who need steady reservoir top-offs without a large installation. Larger operations can compare it against higher-capacity systems.

Key Features & Benefits

• 200 GPD permeate flow — about 8 gallons per hour for reservoir fills.
• Membrane flush valve — lets you flush the membrane to help clear buildup.
• Liquid-filled pressure gauge — mounted on a powder coated steel bracket so you can monitor feed pressure.
• Quick connect feed — 3/8 in RO quick connect input and 1/4 in permeate tube.
• Polypropylene housings — for both the filter and membrane housings.

Who Should Use Growonix GX200-HF

Growers who mix nutrient solutions from filtered water and want a compact, wall-mountable unit. It fits home gardeners and small to mid-size indoor setups on municipal-type supply within the listed feed limits.

Frequently Asked Questions

Q: How much water does it make?
A: It is rated at 200 gallons per day of permeate, or 8 gallons per hour. Actual output depends on feed pressure, temperature and water quality.

Q: What feed pressure does it need?
A: The listed feed range is 40 to 80 psi. A booster pump upgrade, model BP-1530, is listed by the manufacturer for low-pressure supplies.

Q: Can I use it with hard water?
A: The maximum hardness is listed as 0 gpg, so soften hard water before it reaches the unit. Scale can foul the membrane.

Q: What is TDS?
A: TDS means total dissolved solids, the minerals and salts dissolved in water. Maximum feed TDS for this unit is under 2000.

Q: Is chlorine a concern?
A: Chlorine tolerance at the membrane is below 0.1 mg/L, and the unit lists a carbon capacity of 8,000 total gallons. Replace filters on schedule.
