The BulkReefSupply.com TDS Spartan features American made Matrikx and Purtrex filters and virtually all American made Mur-lok dual O-ring fittings. These NSF certified fittings and filters cost us more than inexpensive imports, but set the TDS Spartan apart from the competition.
The BulkReefSupply.com TDS Spartan comes complete and ready to go out of the box. This unit cuts waste water by 50% by using two 150gpd membranes in tandem. At optimal performance it will produce 12.5 gallons of pure RO/DI water in one hour for a total of 300 gallons per day. For optimal performance a psi of 65 is required. Booster pumps are available separately if needed. The Spartan features a Dual and Single TDS meter to give performance readings pre-membrane, post membrane and post DI. This ensures accurate TDS readings at the points where you need them most.
