Aquatic Life High Efficiency Hydroponics 540474 (5-Stage, 200 GPD, Polyresin)

What water pressure is required for optimal performance?

The system requires 65 PSI water pressure for best performance at the recommended temperature of 25°C. If your water pressure falls below 65 PSI, you should consider adding an optional booster pump to achieve optimal filtration rates and membrane efficiency. Low pressure reduces production capacity and may affect the system's ability to achieve the rated 200 GPD output.

How often should I replace the filters and membranes?

Replace the sediment pre-filter every 3-6 months depending on water quality. Carbon block filters typically last 6-12 months. The RO membranes should be replaced every 2-3 years with proper maintenance. The clear housing allows visual inspection of the sediment filter condition. Regular flushing using the manual valve extends membrane life significantly.

Can this system connect directly to my mains water supply?

Yes, the system can connect to mains water through permanent plumbing or using the included garden hose adapter for temporary connections. The adapter fits standard 3/4" outdoor or laundry faucets. For permanent installation, use standard 1/4" tubing with the included press-fit connectors. The automatic shut-off valve protects the system when water supply is interrupted.

What contaminants does this system remove from water?

The 5-stage system removes up to 98% of total dissolved solids including chlorine, chloramines, heavy metals, VOCs, dirt, rust and sediment. The dual carbon blocks eliminate chemical tastes and odours whilst the RO membranes remove dissolved minerals and salts. This makes it ideal for hydroponics, aquariums and drinking water applications requiring ultra-pure water.

How much waste water does this system produce?

Reverse osmosis systems typically produce 3-4 gallons of waste water for every gallon of filtered water. However, the waste water control valve allows you to adjust the waste-to-product ratio. Reducing waste water increases system pressure and speeds up production, though this may slightly reduce membrane life. The automatic shut-off prevents unnecessary waste when not producing water.

Is professional installation required for this system?

No, the system is designed for DIY installation with included components. The package contains hex wrenches, mounting screws, garden hose adapter and detailed instructions. Wall mounting takes approximately 45 minutes using the integrated bracket. Press-fit connectors eliminate the need for special tools and colour-coded tubing simplifies plumbing connections.

What is the maximum TDS level this system can handle?

The system supports incoming water with up to 300 ppm total dissolved solids. Higher TDS levels may reduce membrane efficiency and lifespan. The dual membrane configuration provides better performance with challenging water conditions compared to single membrane units. Pre-filtration stages protect the RO membranes from premature fouling in high-TDS applications.

Can I add additional filtration stages to this system?

Yes, the system accepts optional colour-changing deionization cartridges for ultra-pure applications. The modular design allows integration with other filtration components. Standard 10" cartridges fit the housings, enabling customisation for specific water quality requirements. The dual carbon chambers can accommodate KDF85 chloramine cartridges for enhanced chemical removal.
