Great product, easy to use. By Timothy on 12/15/2014Timothy would recommend this product to a friendGreat product, cheaper than buying prefilled cartridges. Color change is a great visual indicator- best to use TDS meter with system.
Color changing RO/DI Resin By Doel on 12/2/2014Doel would recommend this product to a friendI love this stuff it takes the guess work out of it, no more wondering if it's depleted when it changes color it's used up. I have been using it for the last 2 years on my reef tank supply water filtration and haven't had an algaee out break. It works great and I recommend it to all of you.
Great By Mark on 11/21/2014Mark would recommend this product to a friendGot the refill, so easy to change. Done in minutes and last a while.
great product By fish are friends not food on 11/20/2014fish are friends not food would recommend this product to a friendI love the color changing beads really helps me know when I need to change it. I order at least 3 at a time so I get a better price.
Excellent By Roger on 11/20/2014Roger would recommend this product to a friendA little messy, but pretty easy to use. I love the color change indicator. I wouldn't use any other kind. Foil pouch keep this stuff fresh for a long time.
Always available By Trojan on 11/2/2014Trojan would recommend this product to a friendWhen my D.I. is depleted, it just cost less to do it your self and even if you do you use the already put together canisters, you can always have this set ready, just in case you left your water on and overflow your water storage, and burn out your canister.
Great Stuff By DonB on 11/2/2014DonB would recommend this product to a friendUsed this for years. Always consistent product. Great service before and after the sale.
Great value By Guy on 10/30/2014Guy would recommend this product to a friendAs always fast shipping and great price! Great product! Best way to save extra money for more products! :)
Great Resin By AJ on 10/27/2014AJ would recommend this product to a friendThis is a great resin and as others have said the price is great as well. The only thing that took a little getting used to was knowing when the resin was exhausted. The resin comes with blue/green/gold color in the good resin. When exhausted, it turns brown. Once I figured that out everything was great.
Best item for zero TDS By BG on 10/25/2014BG would recommend this product to a friendBeen using product for over 2 years, never a problem and like how it change colors when you use system. The only DI resin I will buy ever.

Does the color changing di turn noticeable brown? My di has brown in it however you really have to look close to see it.
Bulk Reef Supply 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!

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?
Bulk Reef Supply 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.
Bulk Reef Supply 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.

di resin straight out of a brand new bag already has 40-50% brown in it.. is it already exsausted??
Bulk Reef Supply 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.

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?
Bulk Reef Supply 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
Bulk Reef Supply 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.
