GrowMax Water Reverse Osmosis Membrane 150 GPD for Power Grow 500, Mega Grow 1000, Maxquarium 000 ppm

The GrowMax 150 GPD reverse osmosis membrane is the heart of your Power Grow 500, Mega Grow 1000, or Maxquarium 1000 PPM system . It delivers up to 570 liters of pure reverse osmosis water per day and reliably removes contaminants that could negatively impact plants, microorganisms, or aquarium inhabitants.

What the membrane removes

Thanks to Thin Film Composite (TFC) technology, this membrane filters up to 95% of dissolved solids from the water, including:

• Nitrate, nitrite, ammonium
• Heavy metals such as lead, copper, zinc
• Fluorides, phosphates, sulfates
• Drug residues & micropollutants

The result is soft, pollutant-free water with an extremely low EC value – ideal for hydroponics, compost tea, organic farming or aquaria .

Compatibility & Application

• Power Grow 500 – replaces factory 150 GPD membrane
• Mega Grow 1000 – can be used as a replacement or for performance adjustment
• Maxquarium 000 PPM – important in combination with DI filter to achieve 000 PPM

The replacement takes just a few minutes via the standard housing (11.75") – tool-free and uncomplicated.

Technical data

• Capacity: 150 GPD (Gallons per Day) ≈ 570 L/day
• Type: TFC (Thin Film Composite)
• Filter performance: up to 95% retention of dissolved solids
