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.
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.
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!
Di resin can last in vacuumed sealed bag around 6 months. Feel free to let us know if you have any further questions!
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.
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!
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 :)
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.
Does the job well By Kate on 1/17/2017Kate would recommend this product to a friendEasy to see when the resin needs changing, so my tank always has the highest quality water for water changes

BRS DI RESIGN works amazing! By FLSharkvictim on 11/17/2016FLSharkvictim would recommend this product to a friendIf you like to save money this is 100% the route to go with!! I was buying the SpectraPure® SilicaBuster DI Cartridge - Color-Indicating (DI-SB-CI-10) from Marine depot until I came across this product at BRS.. I dont know about your in coming water but i HAVE TO change out my DI ever 3 to 4 months ballpark. So I have decided to give this BRS bulk DI color resign a try and I am so happy that I did b/c I am saving a lot of money going this route instead buying them already preloaded. One of the better products that BRS makes!!! HIGHLY recommended...
Good stuff By Shanman on 10/16/2016Shanman would recommend this product to a friendI use this and it does what it's supposed to do and it does last quite a while. Also they give you plenty to fill a canister and may even have a little left over.
Better than DI Resin from an LFS By Jim on 10/9/2016Jim would recommend this product to a friendI used to purchase bulk DI resin from a local shop. They kept raising the price and the net volume of DI resin kept decreasing. The last refill only filled up 3/4's of the canister. So I purchased some DI resin from BRS and the canister is now packed to the brim. Well packaged and the quality is excellent. The locally purchased resin only lasted for 10 gallons ro/di water. I expect this resin will last significantly longer with better water quality...........................Jim
Great product By Hambone on 10/7/2016Hambone would recommend this product to a friendGreat product
good product By mareklaguna on 9/29/2016mareklaguna would recommend this product to a friendgood product
works great By geech on 9/23/2016geech would recommend this product to a friendWorks perfectly, definitely tamp the resin down as you load the cartridge. I just use the bottom of a small bottle of prime to pack it in. That'll give you even usage from the bottom up.
Good product. By Sergio. on 9/14/2016Sergio. would recommend this product to a friendVery good product. When the resin changes color, change the resin. It's that simple. :-)
