  • 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.

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.

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.

  • Color change corresponds with rise in TDS By Phillip on 1/29/2016

    Works as mentioned. I wish I could get more life out of it, but chemistry is what it is. It all depends on your tap water quality. As soon as the color completely changes to gold, I see the TDS start to creep up. I generally get a 150 gallons of usable water from hard water after a water softener. I can't attest to the raw water quality's impact on the resin's effect or life though.
  • Good Product By mchammer on 1/23/2016

    This is the first time using this product and it seems to work as advertised.

    This resin is great stuff.I have use nothing else since i have been in the aquarium hobby.I love it,easy to use in any rodi system.It changes color when it is used up even with a meter gauge.It lets you know when to refill with new di resin because it turns from blue to brown.Easy!!!
  • Great product By kiel on 11/25/2015

    Easy to use. Color changing is nice indicator of exhaustion.
  • Excellent By Maria on 11/21/2015

    Great product - always consistent - color changing makings easy to know when it's exhausted.
  • Fantastic! By aptech77 on 11/12/2015

    Fantastic resin. Outlasts the stock resin in my RO Buddie di cartrage by far. Although the RO Buddie is a great unit, i will most certainly be replacing the resin with BRS resin only.
  • Excellent Product By Bruce on 9/19/2015

    This is product is excellent...I love how it changes colour when it exausts itself.
    Love the entire line of BRS products.
