The anion resin is a Type I strongly basic gel resin with an indicator dye that changes from blue to light brown as the resin exhausts.

The higher your membranes rejection rate the fewer TDS your product water will contain resulting in longer lasting resin. The best way to keep the membrane rejection rate up is to monitor and change your pre filters appropriately as well as maintain at least 50 psi going into the membrane. Ensure the resin is packed in the cartridge securely. The resin should be packed very tightly. When squeezed, there should be almost no flex to the cartridge. The initial couple minutes of water from your RO membrane will always be high, this is commonly referred to as TDS creep. Diverting the first few minutes of water down the drain can often greatly reduce DI resin consumption. Maintain low levels of carbon dioxide in your water supply. Excess carbon dioxide will deplete DI resin quickly. If you are depleting resin quickly and have already: addressed the two options above, excess carbon dioxide is the likely culprit. You have two choices: Collect the water coming from your RO system in a large container, add a powerhead or air stone and allow the CO2 to gas off. Then pump the water through your DI resin. Skip all that mess and just buy resin in bulk.   Common Contaminants: Molecule Name Ionic Charge Removed By Sodium +1 Cation Resin Calcium +2 Cation Resin Magnesium +2 Cation Resin Aluminum +3 Cation Resin Ferric Iron +2 Cation Resin Ferrous Iron +3 Cation Resin Chloride -1 Anion Resin Bicarbonate -1 Anion Resin Carbonate -2 Anion Resin Sulfate -2 Anion Resin Nitrate -1 Anion Resin Phosphate -3 Anion Resin Silicate -4 Anion Resin
