I like the color change feature By Earl on 1/13/2013

I am using this in my BRS RODI filter and I get 0 TDS. The fact that it changes color is an added feature that is very helpful, eliminates the guesswork.

Check out the video before you repack and you won't have any issues. Also, I really appreciate products which offer a visual indicator of required action - color changing resin does just that. I still use a TDS meter, I just like knowing what % of the resin is still active.
Great stuff By David on 12/29/2012

Lasts for at least 6 months in my RO/DI. Works great. The color changing feature seems to be a little off, as mine will change colors but still put out 0 TDS.
Awesome stuff! By kelly on 12/19/2012

The fact that it changes color when spent makes it fool proof. 1 cartridge refill is just that and a little more.
Love it! By Jennifer on 12/5/2012

Changes color takes the guess work out of changing it!!
Pound for pound, a great buy By Dave on 12/2/2012

I have ordered this resin multiple times and pound for pound I have yet to find a better value. TDS coming out of my RO/DI system is always 0 and as others have stated, the color tells you when it's time to replace the resin.
Great Product, Great Value By Justin on 11/28/2012

This is a great way to save some money in this hobby. Refilling the cartridge could not be easier, especially with the instructional video here on BRS. My resin seems to last about 8 months. I make around 500 gallons of water with it in that time with an input TDS of around 5-10 ppm, and 0 TDS out. Would definitely recommend this to anyone.
Excellent - Shelf Life Remains to be Seen By Sean on 11/20/2012

Stopped buying pre-flled, non-color changing (all my RO "manufacturer" ever had in stock) DI carts.
Bought a couple of the refillable carts and 7.5 lbs bag of this color changing DI from BRS.
I run it in two stages - the last 2 stages after the membranes, and almost 4 months in, I am finally seeing 30-40% color change (it is very obvious and reassuring) in the FIRST stage. 2nd stage is still completely untouched.
My plan is to wait until the first stage is about 90-95% color changed, then move the cartridge from the second stage to the first stage, and refill the exhausted DI resin and place the "new" stuff in the 2nd stage, since in theory the 2nd stage would remain un-tapped for quite a long time otherwise.
Doesn't clump up in bag easy to work with - just work over a sufrace where if you drop some it can be picked up - like over newspaper or something - lots of tiny little beads that aren't fun to pick out of carpet. :)
Thanks again BRS - and the only thing the jury is still out on, so to speak, is if I should have bought (2) of the single cartridge sized packs instead of the expensive 7.5 lb bag - I have filled the original 2 cartridges and seled and refrigerated the remainder - I hope it is still viable/good when it comes time to refill, or I will have wasted money. The BRS resin lasts much longer then what I was used to, so I really thought I'd be thru it in a much shorter time.
Also consider selling or proving replacement "sponges" for your refillable DI carts.
Easiest Resin for Your DI Needs By Jason on 11/17/2012

Quite possibly the best resin for your RO/DI needs.
Being able to see the color change as the resin quality is diminished is great. I wish all of our chemicals, additives and supplements could tell us visually when they need to be changed.
One of the staples of my reef system. Will forever use it.
Seems to last forever By jlemoine2 on 10/24/2012

I've used color changing DI resin from other vendors before, and always seemed to burn through it relatively quickly. When I consolidated the vendors where I get my consumables, I started using the BRS resin.
I am amazed at how long the BRS resin lasts...it seems to be about 3 times as long. I don't know what is different about it, if anything... but it's a great product and I'll continue ordering it from BRS.
Great Stuff By Tim on 10/24/2012

I love the color changing resin because I know when to change it out. There is no second guessing because it goes from blue to brown so you know it needs replaced. It's easy to replace and Bulk Reef Supply makes it easy to get more because I just need to click reorder.
Quality product, easy to use! By John on 10/10/2012

Love the ease of knowing when the resin is exhausted. Refilling the DI consider is simple and easy. Comes vacuum sealed and ready to use.
