That is where deionization (DI) resin comes into play, by taking place as the last \"filter\" of a RODI system after the membrane. DI resin is ionically charged as either a cation (+) or anion (-) to exchange hydrogen or hydroxide molecules for contaminants like phosphate, silica, nitrate, sulfate, aluminum, iron, calcium, etc allowing you to achieve 0 TDS water for your aquarium and help eliminate any possible water quality issues. You may or may not know that there are multiple types of DI resin available from mixed bed to single bed resins that you can use depending on what the specific goal is for your water and what is in the water after the RO membrane.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMixed or Single Bed\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSingle bed DI resins come in many different flavors, but at heart only contain a single cation or anion that makes up the entire media bed. Single bed resins are commonly used in household water softeners and other applications that require either the positive or negative ion to be removed and exchanged for hydrogen or hydroxide ions. The concentration of a single bed lets you focus on specific issues that you may have with your water without wasting extra resin like a mixed bed resins. Mixed bed resins contain both cations and anions in a single bed of media that will remove both positively and negatively charged ions from the water column. Mixed beds are very common in residential RODI system that is used for reef tanks and other types of aquariums since they are easy to use, but when it comes to efficiency and cost savings, single bed systems are the clear winners.\u003c\/p\u003e\n\u003cp\u003e \u003cstrong\u003eCation or Anion\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCation = Positive Charge\u003c\/p\u003e\n\u003cp\u003eAnion = Negative Charge\u003c\/p\u003e\n\u003cp\u003eChoosing a single or mixed bed resin can be hard especially if you do not know exactly what is in your water or how a RO membrane will filter it.

That is where deionization (DI) resin comes into play, by taking place as the last \"filter\" of a RODI system after the membrane. DI resin is ionically charged as either a cation (+) or anion (-) to exchange hydrogen or hydroxide molecules for contaminants like phosphate, silica, nitrate, sulfate, aluminum, iron, calcium, etc allowing you to achieve 0 TDS water for your aquarium and help eliminate any possible water quality issues. You may or may not know that there are multiple types of DI resin available from mixed bed to single bed resins that you can use depending on what the specific goal is for your water and what is in the water after the RO membrane.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMixed or Single Bed\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSingle bed DI resins come in many different flavors, but at heart only contain a single cation or anion that makes up the entire media bed. Single bed resins are commonly used in household water softeners and other applications that require either the positive or negative ion to be removed and exchanged for hydrogen or hydroxide ions. The concentration of a single bed lets you focus on specific issues that you may have with your water without wasting extra resin like a mixed bed resins. Mixed bed resins contain both cations and anions in a single bed of media that will remove both positively and negatively charged ions from the water column. Mixed beds are very common in residential RODI system that is used for reef tanks and other types of aquariums since they are easy to use, but when it comes to efficiency and cost savings, single bed systems are the clear winners.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCation or Anion\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCation = Positive Charge\u003c\/p\u003e\n\u003cp\u003eAnion = Negative Charge\u003c\/p\u003e\n\u003cp\u003eChoosing a single or mixed bed resin can be hard especially if you do not know exactly what is in your water or how a RO membrane will filter it.

That is where deionization (DI) resin comes into play, by taking place as the last \"filter\" of a RODI system after the membrane. DI resin is ionically charged as either a cation (+) or anion (-) to exchange hydrogen or hydroxide molecules for contaminants like phosphate, silica, nitrate, sulfate, aluminum, iron, calcium, etc allowing you to achieve 0 TDS water for your aquarium and help eliminate any possible water quality issues. You may or may not know that there are multiple types of DI resin available from mixed bed to single bed resins that you can use depending on what the specific goal is for your water and what is in the water after the RO membrane.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMixed or Single Bed\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSingle bed DI resins come in many different flavors, but at heart only contain a single cation or anion that makes up the entire media bed. Single bed resins are commonly used in household water softeners and other applications that require either the positive or negative ion to be removed and exchanged for hydrogen or hydroxide ions. The concentration of a single bed lets you focus on specific issues that you may have with your water without wasting extra resin like a mixed bed resins. Mixed bed resins contain both cations and anions in a single bed of media that will remove both positively and negatively charged ions from the water column. Mixed beds are very common in residential RODI system that is used for reef tanks and other types of aquariums since they are easy to use, but when it comes to efficiency and cost savings, single bed systems are the clear winners.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCation or Anion\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCation = Positive Charge\u003c\/p\u003e\n\u003cp\u003eAnion = Negative Charge\u003c\/p\u003e\n\u003cp\u003eChoosing a single or mixed bed resin can be hard especially if you do not know exactly what is in your water or how a RO membrane will filter it.

DI resin begins depleting when exposed to air. To avoid this, we package all of our DI resin in foil-lined 4mm Mylar bags to prevent exposure to air that may deplete the resin while it is waiting to be used. Our resin can remain packaged this way for 2 years without losing its capacity. Our bulk DI bags are perfect for reefers who process a lot of water or otherwise go through resin quickly. Keep in mind once the seal is opened the resin can start to deplete. Otherwise, purchase the single refill packs for optimal freshness up to two years.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePolymer Structure: Styrene\/DVB\u003c\/p\u003e\n\u003cp\u003ePolymer Type: Gel\u003c\/p\u003e\n\u003cp\u003eFunctional Group: Sulfonic Acid (Cation) \/ Trimethylamine (Anion)\u003c\/p\u003e\n\u003cp\u003ePhysical Form: Spherical Beads\u003c\/p\u003e\n\u003cp\u003eIonic Form (as shipped): Hydrogen\/Hydroxide\u003c\/p\u003e\n\u003cp\u003eColumn capacity: \u0026gt;0.60 meq\/mL\u003c\/p\u003e\n\u003cp\u003eVolume Ratio (Cation\/Anion): 40\/60 percent\u003c\/p\u003e\n\u003cp\u003eWater Retention: 55 to 60 percent\u003c\/p\u003e\n\u003cp\u003eScreen Size Distribution: 16 to 50 (U.S. Mesh)\u003c\/p\u003e\n\u003cp\u003eResin Color: Purple (Cation) \/ Amber (Anion)\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTo get maximum life from your DI resin please takes the following steps\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEnsure optimal operation of your RO membrane.
