The Mantis 4 Stage RO 100 Advanced + TDS & Pump is the ultimate, fully automated water purification powerhouse for serious aquarists. Building upon the standard 4-stage system, this "boosted" model integrates professional-grade electronics to take the guesswork and frustration out of making zero-TDS water, especially for homes with low mains water pressure.

Capable of producing up to 380 liters (100 gallons) per day with a 99.9% rejection rate, it delivers absolute purity for delicate reef tanks, sensitive aquatic environments, and specialized shrimp breeding setups.

  • Stage 1: 5-Micron Sediment Pre-Filter. Protects the system by trapping physical particulate matter, rust, and colloidal debris.

  • Stage 2: 5-Micron Carbon Block. Strips out tap water chlorine, chloramines, and toxic volatile organic compounds (VOCs).

  • Stage 3: 100 GPD RO Membrane. Rejects over 98% of inorganic salts, heavy metals, and bacteria.

  • Stage 4: Color-Changing DI Resin. The final polishing stage to achieve 0 TDS water. The 600mL resin visually shifts from blue/black to golden brown when exhausted.

The "Advanced + Pump" Upgrades:

  • Integrated 24V DC Booster Pump: Automatically increases water pressure to the RO membrane, drastically improving filtration efficiency, speeding up water production, and reducing the amount of waste water produced.

  • Smart Controller & Auto-Flush: Features automated water management, including automatic membrane flushing to prolong the life of your filters, alongside built-in filter change notifications.

  • 2-Point Digital TDS Reader: Continuously monitors the Total Dissolved Solids, providing real-time digital proof of your water's purity without needing manual handheld testing.
