DI Resin 1lb by Resintech

As far as resin goes , it's working. Resin just not a exciting subject to review , but this one is cost effect and groovy. Yeah, I was a child of the 60's. Peace.

Garbage, don't waste your money. Most brands last me about 3 months of water changes on my fish tanks, but this brand only lasted 4 days and both containers are almost depleted.

The resin appears to be good. The packaging was not great as it was one bag rolled up inside of a sealed bag. During transport the grains managed to work their way out of the inner bag and made it messy to deal with them. None the less, fast delivery and good quality. Didn't weigh them but it seemed like the right amount.

Replaced my resin with this stuff and helped a lot. For the people who are mentioning that it exhausts quickly check your RO filter if it's not doing it's job this tries to compensate for the poor filtration and exhausts quickly.

works but doesnt see to last long. ordered this twice. The first batch lasted a while. The second seemed to last 2 weeks. Im trying a new brand this time. If it turns out to be user error or something else then Ill update review. All cartrdiges and membrane were 100% new.

This was a test sample for me and it worked great.

Good value. Works as it should

Under filled, not enough to fill my 10 inch filters. I've ordered 3 total and they all seem to be varying in how much is in them....
