Maxquarium 000 PPM Reverse Osmosis System – GrowMax Water · Ultra Pure Water

The Maxquarium 000 PPM is the definitive water treatment solution for professional growers and aquarium enthusiasts who refuse to gamble with water quality, delivering up to 20 liters per hour of ultra-pure water free from salts and contaminants.

Why you need more than just a standard filter

Many growers believe that simply letting tap water sit to evaporate chlorine is enough, or they rely on basic filters that only remove sediment. They often ignore the invisible dissolved salts, heavy metals, and uncontrolled EC levels present in municipal water, which creates an unstable foundation for any feeding schedule.

The cost of this oversight is high: nutrient lockout, burnt leaf tips, and stunted growth. When your base water already has an EC of 0.4 or higher, you have less room to add the cannabis fertilizers your plants actually need. You end up feeding them "hard water" soup instead of a balanced diet, leading to frustration and lower yields.

The solution is the Maxquarium 000 PPM. By adding a de-ionization stage after reverse osmosis, this system strips the water of absolutely everything, leaving you with a blank canvas (000 PPM). This allows you to control 100% of what your plants consume, maximizing their genetic potential and health.

Use case 1: Precision Hydroponics and Aeroponics

If you are running hydroponic and aeroponic systems, you know that water chemistry is everything. In these soil-less environments, there is no buffer to protect the roots from bad water. The Maxquarium is designed specifically for you. By starting with 0.0 EC water, you can dial in your nutrient solution with surgical precision.

Using this system ensures that every part per million (PPM) registered on your meter comes from the nutrients you added, not from calcium carbonate or lead in the pipes. This prevents salt buildup in the reservoir and drippers, keeping your root zone pristine and your pH levels significantly more stable throughout the grow cycle.

Use case 2: Aquariums and Aquaponics

Beyond cannabis cultivation, the Maxquarium 000 PPM is a lifesaver for marine aquarium enthusiasts and aquaponics gardeners. Fish and corals are incredibly sensitive to the chlorine, chloramines, and heavy metals found in tap water. A standard filter might not be enough to protect delicate marine life.

With its de-ionization filter, this unit guarantees water that mimics the purity of rain. It removes 99% of chlorine and 100% of salts, ensuring that your algae, fish, and beneficial bacteria thrive in a toxic-free environment. It allows you to recreate the exact water parameters required for specific species without fighting against the impurities of your local water supply.

How to choose the best use for you

Not sure if you need this level of purity? Here is how to decide if the Maxquarium is the right fit for your setup:

• If you grow in soil with organic nutrients: You might get away with a standard reverse osmosis filter, but this unit ensures no heavy metals harm your microbial life.
• If you use mineral nutrients in hydro/coco: This is essential. It gives you full control over the EC, preventing nutrient burn.
• If you have hard tap water (High EC): You need this to lower the starting EC to zero, allowing you to use full doses of boosters and additives.

Advantages and benefits that show up in every case

• Total EC Control: Starts your water at 0.0 EC, allowing you to maximize nutrient uptake.
• Root Health: Eliminates chlorine and chloramines that kill beneficial fungi and burn delicate root hairs.
• High Capacity: Produces up to 500 liters per day (20 L/h), enough for large reservoirs.
• Easy Maintenance: Replaceable filters ensure the system lasts for years.
• Versatility: Includes a garden hose adapter for easy connection to standard taps.

Frequently Asked Questions

What water pressure do I need?

For the Maxquarium 000 PPM to function correctly and produce 20 L/h, your inlet water pressure must be at least 4 kg/cm2 (4 BAR). If your pressure is lower, the production rate will decrease, and you might need a booster pump.

How often should I change the filters?

It depends on your water usage and quality, but generally, the sediment and carbon filters should be changed every 4-6 months. The de-ionization resin changes color when exhausted, giving you a visual cue.

Does it remove calcium and magnesium?

Yes, it removes 100% of salts, including Cal-Mag. When using this water, you must add a Cal-Mag supplement back into your mix to prevent deficiencies, which you can monitor with your measuring instruments.

Personal Experience of Pevgrow’s CEO (Alan)

I consider the Maxquarium 000 PPM a mandatory tool when I'm testing new fertilizer lines. If I use tap water, I never know if a reaction is caused by the product or the junk in the water. With this system, I get a neutral base every single time. My favorite use is for flushing plants in the final weeks; using 000 PPM water acts like a magnet, pulling out all the residual salts from the substrate much faster than regular water, resulting in a cleaner, smoother ash.
