Very good resin, and and excellent value. Looks like can fill about 6+ canisters with this 7.5 bag. The color change is very dramatic, you definately know when its used up.

I got this and able to reduce my RO/DI water to 0 ppm and reduce the cost of maintenance my RO/DI system. Very easy to see and use and this bag will last me for 10 months to a year. Awesome!!

Obvious change in color when exhausted. I've used this for years, and produce 0 TDS from the DI!

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.
So much resin! By Michael on 1/10/2011

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!

Good quality, 0 tds. I would still get a TDS meter, because even after it has changed color, TDS is still 0 for a little while.
