2-stage Heavy-duty DI unit for salt water Aquariums and reefs


Model: DI-210



  • The purpose of the DI unit is to further reduce the mineral content of water after RO system.  If you want to achieve very pure water, very low or 0 TDS reading for large amount of water, then this is the unit to get.
  • This can be used with any reverse osmosis system or RO+DI system, also used with all Watergeneral and KoolerMax systems
