Be aware that 100 gpd RO membranes are less efficient than the others with only a 90% rejection rate. It won't lower the TDS as much, and you will go through much more DI resin. Instead opt for a 50, 75, or 150 gpd system which have 98% rejection rate.
Bulk Seef Supply is another great source for RO systems at reasonable prices. Their build quality is also good. Last edited by Myka; 11-03-2009 at 01:15 AM.
