The SpectraPure 300 GPD MaxCap RODI System is a professional-grade water purification unit designed to produce ultra-pure, zero-TDS water for the most demanding saltwater reef aquariums. It effectively removes up to 99.95% of impurities, including troublesome silicates and phosphates, ensuring a stable and pristine aquatic environment. By incorporating high-rejection membranes and laboratory-grade deionization resins, this system provides the highest quality source water, which is the foundation for a thriving reef ecosystem and vibrant coral health.

This system is engineered for high performance and efficiency, featuring dual 150 GPD high-silicate removal TFC membranes for a total output of 300 gallons per day. It includes a 0.5 micron MicroTec Sediment pre-filter and a 0.5 micron Carbon Block pre-filter to protect the membranes and ensure longevity. The unit boasts oversized, high-capacity MaxCap and SilicaBuster SuperDI DI cartridges that offer significantly longer life and lower operational costs. An efficient 2:1 waste ratio, manual flush valve, and two dual-probe inline TDS monitors for checking water purity at four different points make this a comprehensive and economical solution.

Ideal for serious hobbyists, aquarists with large volume systems, or commercial applications, the SpectraPure MaxCap 300 GPD system delivers reliability and precision. Aquarists who need a consistent and large supply of ultra-pure water to maintain sensitive coral species and invertebrates will find this system invaluable. The included TDS meters and pressure gauge provide constant feedback, empowering the user to maintain optimal performance and know exactly when to service the unit, eliminating guesswork and protecting their aquatic investment.
