High Flow Reverse Osmosis Membrane 3000 L – GrowMax Water Replacement

The High Flow Reverse Osmosis Membrane 3000 L is the engine that keeps your high-capacity filtration system running, specifically designed as the original replacement for the GrowMax Water Power Grow 3000 unit. If you are looking to restore the flow and purity of your water to professional standards, this component is non-negotiable to ensure your plants receive exactly what they need, without the impurities of tap water.

Is your water quality sabotaging your harvest?

Problem: You invested in a high-capacity osmosis system, but lately, you've noticed the flow is slower than a dripping tap, or worse, your EC meter is showing higher levels than usual. Membranes don't last forever; over time, they get clogged with the very sediments and salts they are meant to stop.

Agitation: Ignoring this is a rookie mistake that costs money. Using a worn-out membrane means you are feeding your plants chlorine, heavy metals, and uncontrolled minerals. This leads to nutrient lockout, pH fluctuations, and clogged Drip irrigation systems. Basically, you are gambling with the health of your entire crop and wasting expensive nutrients that can't be absorbed properly.

Solution: The solution is a simple swap. By installing a new High Flow Reverse Osmosis Membrane 3000 L, you instantly reset your system to peak performance. You get back that massive flow rate and the peace of mind that comes with starting from a clean slate (low EC) every time you water.

Quick spec sheet of the product

• Brand: GrowMax Water (Official Replacement).
• Compatibility: Power Grow 3000 and Mega Grow 1000 (requires 2 units).
• Production Capacity: Up to 3,000 liters per day.
• Flow Rate: Approximately 125 liters per hour.
• Filtration Power: Eliminates 95% of salts/heavy metals and 99% of chlorine.
• Material: High-durability semi-permeable polyamide composite.

Key advantages over generic replacements

Not all membranes are created equal. When you are running a medium to large-scale operation, you cannot afford inconsistent filtration rates or membranes that degrade after a few weeks of heavy use.

• High Flow Technology: Unlike standard residential membranes that trickle, this beast is built to deliver 125 liters per hour, meaning you spend less time waiting for tanks to fill.
• Precision Filtration: It maintains a consistent rejection rate of salts, ensuring that when you mix your Cannabis fertilizers, the EC is determined by the food, not the background noise of the water.
• Durability: Constructed to withstand higher pressures and continuous usage cycles typical in Hydroponic and Aeroponic Systems.
• Eco-Efficiency: Designed to optimize the waste-to-product water ratio, making it more environmentally friendly than older generation membranes.

Real benefits you’re going to notice

First, the speed. If you have a large reservoir, filling it becomes a quick task rather than an overnight chore. This efficiency allows you to react faster to your plants' needs.

Second, the control. With 95% of dissolved solids removed, your starting water is essentially a blank canvas. This means no more guessing games with CalMag deficiencies or toxicities caused by mysterious tap water additives. Your plants will show vigorous growth because they are drinking pure H2O.

Step-by-step installation guide

1. Safety First: Turn off the water supply to your RO unit and open the flush valve to relieve pressure.
2. Open Housing: Unscrew the membrane housing cap (you might need a housing wrench).
3. Remove Old: Use pliers to gently pull the old membrane out. Note the direction of the flow arrow or seal position.
4. Clean: Rinse the inside of the housing with a little hydrogen peroxide or mild soap to remove biofilm.
5. Insert New: Lubricate the O-rings of the new membrane with a little water (no grease!) and push it in until it seats firmly.
6. Flush: Close the housing, turn the water on, and let the system run for 30-60 minutes, discarding this initial water to clear out preservatives.

Frequently Asked Questions

How often should I change this membrane?

It depends on your input water quality (EC) and usage volume. Generally, for high usage, every 6 months to 2 years. If your product water EC starts rising significantly, it's time.

Does this fit other brands?

It is standard sizing for high-flow housings, but it is specifically engineered for GrowMax Water systems like the Power Grow 3000. Always check your housing dimensions if using a different brand.

Why is my flow rate lower than 3000L/day?

The 3000L rating is based on optimal conditions (usually 60 psi pressure and 25°C temp). Lower water pressure or colder water will reduce the production rate naturally.

Do I need to change the carbon/sediment filters too?

Yes! To protect this expensive membrane, you must change your sediment and carbon pre-filters regularly. If you don't, chlorine will destroy the membrane material quickly.

Personal Experience of Pevgrow’s CEO (Alan)

Look, if you are growing in soil with a couple of pots, maybe you don't notice the difference. But when I'm setting up a hydro system or managing a large room, this membrane is the MVP. I've seen growers chase nutrient deficiencies for weeks, buying every bottle on the shelf, only to realize their base water was 0.8 EC straight from the tap. With this membrane, I start at 0.0 or 0.1 EC every single time. It gives you total control. Just remember to flush it regularly; treat it well, and it will save you so many headaches down the line.
