Max Water 6 Stage Aquarium System (Clear, 358L/Day)

What water pressure do I need for this system to work properly?

The system operates within a pressure range of 45-70 PSI, which covers most UK household water supplies. If your pressure falls below 45 PSI, you may need a booster pump to achieve optimal performance. The included pressure gauge helps you monitor your water pressure and system efficiency.

How often do I need to replace the filters?

Filter replacement depends on your water quality and usage. Typically, the pre-filters need changing every 6-12 months, whilst the RO membrane lasts 2-3 years. The DI resin cartridge requires replacement when TDS readings start rising above zero. Monitor your TDS meter readings to determine optimal replacement timing.

Can I use this system for drinking water as well as aquarium use?

Yes, this system produces ultra-pure water suitable for drinking, though many people prefer to remineralise it slightly for taste. The six-stage filtration removes virtually all contaminants, making it safe for consumption. However, the zero TDS water lacks beneficial minerals that some prefer in drinking water.

What's the difference between RO and RO/DI systems?

RO systems remove most contaminants but leave some dissolved minerals, typically achieving 95-98% purification. RO/DI systems add a deionisation stage that removes remaining dissolved solids, achieving 99.99% purification with zero TDS. The DI stage is crucial for sensitive aquariums and hydroponics where even trace minerals can cause problems.

How much waste water does this system produce?

Like most RO systems, this unit produces approximately 3-4 litres of waste water for every litre of pure water. This is normal for reverse osmosis technology and necessary for flushing contaminants away from the membrane. The waste water can be collected for garden irrigation or other non-critical uses.

Do I need any additional equipment to install this system?

The system includes most necessary components, but you may need specific fittings depending on your water source connection. Some users add a TDS meter for monitoring, a flush valve for membrane maintenance and a float valve for automatic shut-off. These accessories enhance performance but aren't essential for basic operation.

What temperature range can this system handle?

The system operates safely between 4°C and 40°C (40-104°F). Water temperature affects membrane performance - colder water reduces output whilst very hot water can damage the membrane. Room temperature water provides optimal performance and membrane longevity.

How do I know when the DI resin needs replacing?

Monitor your output water with a TDS meter - when readings rise above 1-2 ppm, it's time to replace the DI cartridge. Fresh DI resin should produce 0 TDS water. The resin colour may also change from its original state, though this varies by manufacturer and isn't always a reliable indicator.
