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.

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.
Answer by: Bulk Reef Supply on Dec 22, 2013 6:42:00 AM
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.
Answer by: Bulk Reef Supply on Jan 4, 2014 11:12:00 PM
What are the 'beads' for the DI made of? Is this something that can be thrown away in the trash after it has been depleted? Are they plastic based - such as microbeads that will break down into smaller and smaller pieces?
Question by: Aron on Dec 4, 2016 2:39:00 PM
Hey there,
While there are a few different resins available, most DI resins will be made of a porous polymer called polystyrene sulfonate. There is nothing toxic about the media itself and should be fine to dispose of in your regular trash. Have a great day!
Answer by: Zack (Admin) on Dec 21, 2016 1:45:00 PM
One of my resin filters looks solid grey from the top down (the bottom inch or so looking normal). Although I changed the resin filter not long ago, I changed it out again today. Packed it with new resin from a new, unopened foil pack, and as soon as the water filled the canister it turned that grey color again. I have to assume it must be air bubbles, but but it's so solid looking. there must be an air bubble enclosing each granule of resin to produce this effect. Honestly it looks like concrete. Any idea? I've never had this happen before.
Question by: Meg on May 28, 2017 4:50:00 PM
The grey appearance is likely the result of air on the inside surface of the cartridge, as you guessed. It would be nearly impossible for the media to actually be exhausted that quickly, and even if it were, it would change to a brown/orange color, rather than grey. I would ensure that your media is tightly packed to avoid the possibility of channeling in the media, and you may also want to give the unit some time to run as much of the air will likely get purged after a while and once the media is fully wetted it would darken in appearance.

Hope this helps!

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!
Answer by: Connor (Admin) on Apr 19, 2016 12:13:00 PM
Does this Di resin remove silicate?
Question by: Louie Pistorino on Apr 4, 2016 7:56:00 PM

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!
Answer by: Bulk Reef Supply on Sep 6, 2013 10:38:00 AM
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.

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.

  • Great product By chris on 6/8/2017

    I love the color changing DI resin. It makes maintenance on RO system so much easier to be able to see how much life is left in my DI cartridge with a quick glance. Comes in a great re-sealable bag too.
  • Easy simple replacement. By Blake S on 6/5/2017

    Makes changing out DI resin simple. Fits the standard 10in chamber with a small amount left over.
  • Great product By Don on 6/2/2017

    Works as intended. Great quality product.
  • GREAT PRODUCT By STEVEN on 5/23/2017

    I haven't used any other brand. Tried it first and have stuck with it.
  • Awesome and must have By Justin on 5/20/2017

    If you have a reef and are concerned with your water, you need this stuff. I prefer the color changing to any other version because it visually lets you see when you are spent vs. wondering if you need to change your resin or not. A must have for any reefer with an RODI system.
  • Always Great By Ken on 5/17/2017

    Bulk reef DI never fails me
  • 5/5 By Brian on 4/9/2017

    I have no problems with this product, I ended up re-vacuum sealing the 7.5lb bag into a few smaller bags since it will last for months.
  • My go to resin By Fokai on 4/8/2017

    This continues to be my go to for resin. Great product at a great price
  • Quality Color Change Resin By Patrick on 4/7/2017

    Ordered the 1.25lb pack, enough for a single canister. BRS is awesome and gives you a bit more resin than you need, just in case you mess up and spill a little bit (like me). Fast and free shipping, perfect quantity of resin, great price.. other than that, not much else to say!
  • Great product By Paul on 4/4/2017

    Works just as it should. Changes color when exhausted
  • Do resin By Dan on 4/1/2017

    Great product. Wouldn't use anything else.
  • Excellent Product By Happy Hunter on 3/29/2017

    The color change is awesome and this comes nicely packaged in a vacuum sealed bag. The larger bag provided a nice bulk discount.
