Why Choose the RODI Reverse Osmosis Marine Aquarium Fish Tank Filter (ROP4-DJ)?

The ROP4-DJ is a high-performance 4-stage Reverse Osmosis Deionisation (RODI) system designed specifically for marine aquariums and fish tanks requiring ultra-pure water. Assembled and tested locally, it delivers 0–0.5 ppm TDS, removing virtually all impurities for the healthiest marine environment possible.

Unlike standard RO systems, the ROP4-DJ features an integrated pressure pump, ensuring consistent membrane pressure and optimal filtration efficiency — even in low-pressure households. This allows for improved output, extended membrane lifespan, and consistently pure results regardless of varying mains supply conditions.

Compact Design and Powerful Performance

Constructed from high-quality, BPA-free food-grade materials, the ROP4-DJ combines a sediment pre-filter, carbon block, TFC membrane, and mixed-resin DI stage to deliver unmatched purity. The built-in booster pump ensures that every stage operates at ideal pressure, achieving near-perfect contaminant removal and maximizing water production rates.

Seamless Integration and Compliance

The complete kit includes everything required for installation — fittings, tap, tank, and all compliance accessories. Each system is pressure-tested before dispatch and meets Australian Standard AS3497 requirements.

Backed by a 36-month warranty, the ROP4-DJ offers proven reliability, powerful purification, and effortless integration into any marine aquarium setup.
