GrowMax Water Maxquarium 000 PPM - Up to 500 L/day

The GrowMax Water Maxquarium 000 PPM is a highly efficient complete reverse osmosis system with additional deionization (DI) . It delivers completely mineral-free water with a total solids content (TDS) of 0 PPM – ideal for applications with the highest purity requirements, such as aquariums, hydroponics, laboratory analysis, or high-quality plant cultivation .

5-stage filter system for highest water purity

The Maxquarium system combines proven reverse osmosis technology with a downstream DI filter to remove even the finest residues from the water:

1. 5 µm sediment filter – removes rust, sand and suspended matter
2. GAC activated carbon filter – removes chlorine, chloramines, herbicides & VOCs
3. RO membrane (TFC 200 GPD) – removes up to 99% of dissolved salts & metals
4. Post-carbon filter – removes odors & improves taste
5. DI resin filter (Mixed Bed Resin) – reduces the TDS value to 000 PPM

The result: absolutely pure water , free from salts, nutrients, heavy metals, pesticides, nitrate, fluoride & Co.

Ideal for demanding applications

The system is particularly suitable for:

• Aquariums (marine & freshwater) – for optimal water quality & stable values
• Hydroponics & aeroponic systems – for precise fertilization with soft water
• Laboratory & technical applications where ultrapure water is required
• Organic plant cultivation & compost tea – to safely eliminate chlorine & residues

Installation & Maintenance

The system connects to standard faucets using the included adapter (also available for garden hose or under-sink installation). It operates pressure-based, without electricity , ideally at 3–5 bar line pressure.

Recommended replacement intervals:

• Sediment & carbon filters: every 4–6 months
• RO membrane: approx. annually
• DI resin filter: depending on TDS value and consumption (more common with hard water)

Replacement filters are available as a complete set and can be replaced without tools thanks to the quick-release system.

Technical data

• Capacity: up to 500 L/day (approx. 20 L/h at optimal pressure)
• Filter stages: 5 (sediment, GAC, RO, post-carbon, DI resin)
• TDS value of the source water: 000 PPM
• Water pressure: optimal 3–5 bar
• Power consumption: none
• Connection: ¼" Quick Connect, tap adapter included

The Maxquarium 000 PPM is the best choice when absolute water purity is crucial – reliable, efficient and ideal for aquarists, hydroponics and professional gardeners .
