Quick Overview

DI Resin is necessary to reduce Total Dissolved Solids (TDS) to zero and is the last stage of an RO/DI unit. It is not necessary to use the expensive proprietary DI cartridges that other RO manufacturers sell. Simply buy a refillable DI cartridge if you don't have one already and fill with DI resin. You'll save money and get the same results.




Nuclear Grade Mixed Bed DI Resin



  • 1.5 Gallon - Fills 6 standard 10" refillable cartridges

  • 1.25 lbs. - Fills 1 standard 10" refillable cartridge

  • Vacuum packed in foil-lined 4mm Mylar bags to preserve quality (see Full Details for more info)

  • 2 year shelf life (unopened)

BulkReefSupply.com takes pride in the proper packing of our DI Resin. DI resin begins depleting when exposed to air. To avoid this, we package all of our DI resin in foil-lined 4mm Mylar bags AND vacuum seal it so no air is left in the package to deplete the resin while its 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. The bags are resealable via a featured zipper lock. Keep in mind this won't be as good as the original seal so we recommend them only for reefers who need a high volume of DI Resin. Otherwise purchase the single refill packs for optimal freshness up to two years.

 

To get maximum life from your DI resin please takes the following steps

 

  • Ensure optimal operation of your RO membrane. 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 prefilters appropriately as well as maintain at least 50psi 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 though your DI resin.
    • Skip all that mess and just buy resin in bulk.

  • Way to go By Bruce on 3/18/2015

    Getting zero TDS and good resin life. Easy to refill cartridges and way cheaper too.
  • good product By tony on 3/15/2015

    Seems to last longer than the color changing type. TDs goes to zero as soon as reactor is turned on
  • The DI resin By chuck on 3/10/2015

    I have used BRS Bulk Deionization Resin several times. When my TDS readings start going up, I automatically change the DI Resin and the TDS reading is right back to .000. The price is a good price for me, the product works.
  • Awesome stuff By Jeremy on 2/5/2015

    This DI resin works better than anything I've tried on the market while also being very cost effective.
  • A+ By Reeflover on 12/31/2014

    Tremendous product! I have a TDS reading of over 450 out the tap & absolute zero using BRS DI!!!! Great product & allows my reef tank the purest water possible!
  • Works as expected By Jimmy on 12/31/2014

    It works great. lasts longer than color changing type.
  • Awesome By DBLAKE62 on 11/9/2014

    TDS ZERO CANT GET BETTER THEN THAT!
  • Awesome stuff By DBLAKE62 on 11/9/2014

    Vacuum sealed quality preformance you can count on. Each package contains the highest quality resin you can buy.
  • Great stuff By shovelrider on 9/29/2014

    This stuff does what it is supposed to do. I get about 6-8 months of 0 TDS with this resin with my water quality. Replacing the resin is easy as well with the BRS cartridges. High quality and great price!
  • Longer lasting By David on 9/21/2014

    I had been using the color changing resin, though I have a TDS meter. I switched to this product and I am much happier. I am finding it lasts a lot longer than the color changing! Highly recommend!
  • Great Product! By Josh on 9/15/2014

    TDS instantly went down to 0 from 32. Works perfectly!
  • Outstanding! By Paul on 5/14/2014

    I've been relying on BRS from the get-go and the DI resin is one of the products i regularly need. I've used the regular kind in stead of the color changing type and with the same positive results. I re-ordered and i was pleasantly surprised when i opened the box as they included an extra unit.... That made my day
