  • BRS Bulk DI Resin - Color Changing

Quick Overview

Why does BRS recommend this?


We recommend color changing resin for the fact that it will physically change colors as it gets exhausted.  That allows you to monitor the consumption of the DI resin and know when to change it out.  If you have a TDS meter we still recommend color changing resin as it will let you know when to monitor your TDS meter for when TDS starts creeping through the DI resin.  When it comes to packaging not just any packaging will do, we package our DI resin in vacuum sealed Mylar bags for ultimate effectiveness and shelf life.


DI Resin is necessary to reduce Total Dissolved Solids (TDS) to zero and is the last stage of an RO/DI unit. Resin is sold in economical bulk bags as well as single use pouches. The resin is designed to be used with one of our refillable DI cartridges. This refillable design saves a small fortune over proprietary sealed cartridges.


Color Changing Mixed Bed DI Resin



  • Changes Color from Blue to Brown as the media is exhausted.

  • 1.5 Gallon - Fills 6 standard 10" refillable cartridges

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

di resin straight out of a brand new bag already has 40-50% brown in it.. is it already exsausted??
Question by: john on Dec 22, 2013 6:42:00 AM
Hi John,
No it is not. Half of the DI resin beads are always brown and half are blue. The brown always stay brown and the blue resin changes from blue to clear as it is exhausted giving the appearance that the entire cartridge has turned brown.

I noticed that your DI resin is vacuum sealed. If I purchase the larger bag that has 6 changes in it, once I open the bag, it will no longer be vacuum sealed. Will this affect the product in any way?
Question by: Earl on Jan 4, 2014 11:12:00 PM
Hi Earl,
If you use the resin quickly it wouldn't have any sort of noticeable effect if you close the seal after each use but if you are purchasing and planning it for long term storage then you would be better off purchasing the individual bags.

How long will the DI resin last in a non opened vacuum sealed bag?
Question by: Kevin Schulze on Apr 14, 2016 5:47:00 PM
Great question!
Di resin can last in vacuumed sealed bag around 6 months. Feel free to let us know if you have any further questions!

Does this Di resin remove silicate?

Ok, I'm using a color change di resin now, not BRS, but same principle. I'm kinda new to ro/di making. The bottom of my cannister has a light brown color too it now that goes up about 2 inches. TDS is still at 0. Do you change it when just a little brown going up or wait till whole cannister has turned brown? Sorry to be so naive but like I said not been doing this long. Thanks for any suggestions you may have.
Question by: Valerie on Jan 29, 2014 7:51:00 AM
Hi Valerie,
You want to wait until the TDS starts to read above 0 as the TDS meter is the ultimate say, but generally speaking that is going to correspond with the DI resin turning almost entirely brown.
Answer by: Bulk Reef Supply on Jan 29, 2014 7:51:00 AM
Does the color changing di turn noticeable brown? My di has brown in it however you really have to look close to see it.
Question by: Andrew on Sep 6, 2013 10:38:00 AM
Hey Andrew,
The DI resin changes from a dark blue/black color to a light gold yellow color. You should easily be able to tell from across the room!

Recently purchased a number of small individual vacuum sealed pouches. Is it better to store them in a fridge or freezer for prolonged life, or will room temp be more sufficient?
Question by: Travis on Jul 31, 2014 12:22:00 PM
Hi Travis,
The main enemy of DI resin is exposure to co2, which is why we use the Mylar foil lined bags and then vacuum seal them. Just store the bags in a room temperature place and you will be just fine :)

Will your RO/DI filters fit my Coralife II
Question by: Alan Cox on Feb 8, 2014 4:03:00 AM
HI Alan,
They sure will. All of the above (and basically any RO/DI unit) uses standard 10" cartridge sizes.

Full Details

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.

  • Does its job By Tracy on 7/13/2016

    Its all I buy...works like its suppose to.
  • Great product By stephanie s on 6/6/2016

    This product is number one in the industry and I don't use anything else. Kudos to BRS in carrying this product and being able to ship it same day or next. I recommend you keep left over product in a plastic bag in the fridge until you need to reorder.
  • Trippy color changer By Larry on 6/6/2016

    Works great and changes color very easily to see in canister. Don't get consistent runs though. I swap out my other sediment and .5 carbon micron filters at the same time just to get it done. pressure still the same, but last 2 changes have run out quicker than the last batch with no change on usage.
  • Fantastic resin. By Mark on 6/4/2016

    This stuff works great. I know BRS says it will last up to 6 months in the vacuum sealed bag, but it lasts way longer than that. I have had mine for more than 8 months and it is still effective. I run 2 DI chambers on my unit and it lasts a while and I get 0 TDS from my unit with the BRS color changing resin.
  • Great media, best price. By Earl on 5/24/2016

    This is the only deionizer resin I buy. It is packaged well, and is the best price I have found.
  • Great buy as always By kelson on 5/1/2016

    Perfect replacment for when your DI resin needs to be changed out!
  • Great Product By Al on 4/9/2016

    5th time I bought resin, great stuff.
  • Excellent By Tim on 4/7/2016

    Easy to use, know exactly when it is used up.
  • Works Great By Lou on 4/6/2016

    Just received a new DI resin bag and it's packed and shipped well. I added it to my unit and instantly back at 0 TDS. The color changing is great and gives you and idea as to when it needs to be changed. No nonsense. Just works.
  • Great product By Samuel on 3/28/2016

    Excellent packaging and easy to tell when the di needs changing.
  • Exactly what I needed. By Blake S on 3/21/2016

    Ordered this to refill my DI resin container. It was just the right amount. Very easy to tell when it is exhausted.
  • Perfect Every Time By Steve D on 3/21/2016

    I have purchased the larger 7.5 Lb and it refills your DI cartridge at least 6 times with a little left. The color change starts from the bottom, moving up so you know when its getting time to change. I always purchase my DI from BRS as I use their RODI unit also. Product is very consistent as is shipping. Can't go wrong here.
