In many applications, the MAXCAP® DI™ (DI-MC-10) is installed up-stream of a Mixed-Bed or Hi-Silica removal cartridge. For example, if the RO water entering the MAXCAP® DI™ has 20 ppm TDS (Total Dissolved Solids), the original DI cartridge may process about 400 gallons of pure DI water. By placing a MAXCAP® DI™ cartridge in front of the original cartridge, 1200 gallons of water will pass through both cartridges before the MAXCAP® DI™ is exhausted. The original DI cartridge will be only one-third exhausted. A second MAXCAP®DI™ will process another 1200 gallons and the original cartridge will now be two-thirds exhausted. Only after a third MAXCAP® DI™ cartridge processes another 1200 gallons will the original cartridge finally become fully exhausted. 

That's 3600 gallons purified with only 4 (3 MAXCAP® DI™ + 1 Mixed-Bed) cartridges, not 9 (9 x 400 = 3600).

Everything you need to add a dual stage DI to your existing RO system. SpectraPure, Inc.® Revolutionary MaxCap® DI ™ cartridge has over 3 times more capacity than any other Mixed-Bed or Hi-Silica removal deionizing cartridge. Install after your existing RO system to remove any unwanted algae growth in your aquarium. This incredible break-through in DI cartridge technology will enable you to produce DI water at less than half of any other dual stage DI systems.
