Great! By Brennan on 12/13/2011

I bought it with the refilable cartrige to save money but turns out this is better than every other DI I've used! In the past I've used cartrigest from coralife and the package deal cartrige from the "another" popular website. I NEVER had 0 tdi, though maybe my meter was off. Now I read 0 even with my old (2+ years) ro membrane. I think the secret is that it's sealed so well and also that you pack it real nice yourself (and that packing later doesn't get messed up with shipping). Only suggestion is that they should provide replacement bottom foam with the resien, my foam seemed to get a bit mangled when screwing the bottom on..

I was buying the premade kent cartridges until I started using the bulk DI resin. I save a ton and get close to 7 refills which can add up quickly when buy the premade one. I have well water and my TDS always comes out at 0, this stuff is the best.

I've done quite a few hundred gallons since purchasing this stuff and I'd have to say that it's holding up much better than the "manufacturer" brand. Color is just fine whereas the other stuff would have started to change on me already. Not sure what to think other than it's higher quality.
Good Stuff but... By David on 10/8/2011

Good stuff but I am going to save the little bit of money because I use a TDS meter and I don't need the color change. I found that by reading TDS the resin works well past the time it changes color.
Saves you money and very easy to do By Sarah on 9/17/2011

I got tired of spending so much for DI resin cartridges that I thought I would give this a try. It was so easy to do that I wondered if I did it right. I am happy to say that I did do it right and my ro unit does not know the difference. My output reads zero tds! I will be back for more when I need it.
So nice to use. By Ryan on 9/5/2011

I used to buy the cheapest resin I could find, and only knew when you change it by testing TDS or by the smell of the water. We have really bad water so occasionally it would go south before I could tell and I would get nuisance algae outbreaks. The color change beads make it easy to tell how much time I have left. Started changing right away from the bottom up, so I feel much more confident about my RODI quality.

Once you refill your DI cartridge one time it is not difficult at all.
DI resin does have a shelf life so don't buy bulk unless you need it within a few months.

I purchased this to replace the DI resin in my Vertex RO/DI unit. It works very well but doesnt last as long as the original product that came with the unit. Still a very good deal considering the price diffrences. I may have to replace the DI resin often but Ill be saving $$$$ in the long run.

We have extremely hard water where I live with fluctuating tap TDS that ranges from 330's and spikes to nearly 600! Regardless of the source water, since I have changed to a dual DI canister system - my final TDS is always 0. Unbelievable!!!

I really like that I'm able at a glance see the color change intheDi that it will need to be changed. I have a TDS monitor on the system, but have learned no need to keep checking it until the color is close to being gone. I'm completely happen with the product.

It's nice to have this color changing resin, but it usually changes long before it's exhausted. I still use a TDS meter to maximize the use and only change it when I see a 1ppm reading.

Great stuff-you can cram it into your container of choice, then pound it on the table, and it doesn't even cry. Now that's selective breeding at it's best. (LOL)
Then, when you're finished using it, you can pure it onto the floor, and lean your head back and dream that you are at the beach while you wiggle your toes in it.
Ahhhh, Bulk Reef Supply..... your da man!!!!!!

Being able to know if your resin is still working by one quick glance is awsome. No more do I have to guess if I need to change my resin out.

This is the best way to save money and get crystal clear water at the same time. Lets you know when its time to change and works great. I was spending $52.62 in this cartridge at my local pet shop and now I dont mind paying and making sure i change it on time now on. Super product and better price gets 10 stars in my book...

The color changing resin is great. You can easily tell when the resin is nearing the end of its life, so I monitor the TDS meter more closely to ensure I maximize the use of the product. The 7.5lb bag is great as I do pretty frequent water changes (about every other week) due to the load within my tank.

My water before RO is 330 after running through a Bulk Reef Supply RO unit and through this resin it is at 0. I like how you can monitor when it is time to be chaged out. I would still invest in a tds meter because I can still run a couple hundred gallons of water after it has changed color. Thumbs up as usuall to Bulk Reef Supply for a great product at a great value.

This replacement DI resin is awesome, you receive more resin then you need, and can fill the canister all the way to the top. My last DI replacement filter didn't come with near this much resin inside, and was twice the price - total value here!

I tell people all the time at the Lfs u are crazy for not refilling your own cartridges. For the cost you save in filling your own you can buy yourself something really nice for your tank. After purchasing 6 refila so far I've saved $120 compared to Lfs di filter costs. And I'm sure the Lfs is doing the same thing.

You really get your moneys worth here, I burned through 1000 gallons and it is still reading 0 TDS on the exit. I know every water supply is different but this stuff is going to last a long time and I under-estimated just how much 1.5 gallons would be, its pretty heavy. The color changing feature is really nice, although probably a bit redundant with a TDS meter, still I think its cool.

I go through alot of water on my reef system. BRS has by far the best DI resin that I have come across in a long time. My citys water is very hard for my ro unit to get fully stripped of minerals. With this DI resin in my system the water is 0 TDS and very pure. My corals thank you!
Way above my expectations... By Michael on 11/10/2010
Michael would recommend this product to a friend
I was concerned that a "1 refill" container may not be exactly enough, but whoa was I wrong. It is probably a 3 times refill quantity.
I bought an RO/DI from an ebay site and have had fair luck with it. I got a refill on the DI through them the next time and my PPM were between 12-24. I thought that it was way better than the 145 I was getting before, so I accepted that as good enough. Now with Bulk Reef Supply, instantly my ppm went to zero, "0", zilch, nada. I am giddy with excitement for my corals, and can't wait to see the color change so I don't have to play any guessing games anymore.
As for price, well, I am very satisfied with that too.
Thank you from a new lifetime customer,
