5 Stage Aquarium Reef Reverse Osmosis Water Filtration RODI System | 100 GPD
  • This product is great for aquariums, laboratory testing, and other applications where ultra-pure water is necessary.
  • 1st Stage - All of our sediment filters use multi-gradient spun polypropylene filter cartridges. These cartridges use the entire depth of their media by trapping the largest sediment particles on the outside of the filter, then gradually stepping down the size of particles they will reject as the water moves closer to the core of the filter. The result is longer filter life, greater dirt-holding capacity, higher flow rates, and remarkably low pressure drop.
  • 2rd Stage - With carbon block filters, water is forced through the pores of the densely compacted carbon block, where a combination of mechanical filtration, electrokinetic adsorption, and physical/ chemical adsorption take place to reduce a wide range of contaminants.Solid carbon block filters do not remove healthful, naturally-occurring minerals.
  • 3rd Stage - Sediment 1 MICRON. 4th Stage 100 GPD RO Membrane. 5th Stage- Mixed Bed DI Resin Filter
  • Designed for city water use, incoming TDS should not exceed 350 TDS. Pre-Assembled in California, USA. Extremely simply installation and easy to use!
