If you have a TDS meter buy it. By Joe on 3/23/2013

My incoming TDS is 1100-1420 so I go through a lot of resin on a regular basis. Color changing resin works great without a TDS meter but depending on my incoming numbers I normally get 5-7 more gallons per cartridge refill with the non color change resin. They both work great but for those of you that have a meter go with the non color change. One more thing, no matter how much or how hard I pack the refill there's always a gap or room in the cartridge with the nuke grade after 25gals or so compared to the color changing.

Works like a charm. Long lasting for my area (central FL). The amount in the packet fits perfect in the refilable cartridge. I buy 2 at a time so that I always have some on hand.

i like this item better then the color change kind. saves a few bucks and seems to last a little longer. i use the meter to check when to change out anyway.
If you have TDS meter, this is a great way to save money. By Al on 1/28/2013

Bought this product because they were back ordered on the color changing DI. It has worked fantastically. Changing when the TDS coming out of the DI climbs from zero is how you know when to change it out.
Great Product! By wesley on 9/17/2012

works just as great as the color changer but id recommend having a tds meter with this one so that you know when its depleted

If consistan .000 TDS readings from your RODI unit is what you are after, then this is the stuff for you! You could buy another brand of resin from one of the other online retailers... but why would you want to? This stuff works excellent and lasts a long time to boot. Good prices (not just on Deionising resin... but on everything!), great service, and fast shipping!!!

Bought this resin to refill my spectrapure 90 gpd unit. The amount of resin in this package was perfect. It filled the canister tightly even after packing it down several times. Have had this resin running for several months and still getting a consistent 0 tds reading, making 25 gallons every other week. Highly recommended.

Bought this or my 5 stage system. Remove canister, open pouch and pour in. Couldn't be cheaper or easier. Thanks BRS!

I recommend you have your own TDS meter, but this stuff is great. Do not have any doubts on refilling your own RODI filter. It takes a few seconds and saves you a few bucks.

I own a "name brand" RODI unit, one that it turns out I overpaid significantly for. As I learned more about this hobby I am thankful for BRS, who offer products like the generic DI resin. Good low price, easy to use, and solidly 000 TDS on my tests keep reef costs down, and my water quality is perfect. Don't hesitate, try the BRS RODI stuff.

My tap to R/O water is .000 PPM using this DI resin with a 75 GPD Dow membrane purchased from BRS as well. Why pay more? My water is ultra pure using this product, exactly what I'm looking for.
best product By Jeffrey on 10/17/2010

Resin is fresh, not dried out and therefore last the longest. Definite value for money especially in larger quantities. Switched from another supplier, foil packaging, I think, makes it last longer.
