Review on 🐠 Kolar Labs - LANXESS DI Color Changing Deionization Resin for Fish Tanks, Ponds, and Aquariums - Premium Grade for Reef Aquariums by Jane Cuperus

I gave it 5 stars at first because it deserved it. Not now. See below. Update July 2019 This is the last time I will buy this product. As another reviewer noted, the bad weight isn't 1.25 pounds. I've bought this 3 times though Revain. This is the third. The other 2 times I had to pack it into the Ro case so tightly that I had some left over. Lately? To kid. Not only that, there was 1 inch of space left after filling. After only 75 gallons were made, half the resin had already changed color. Used to easily extract hundreds of gallons from a canister. This should be avoided at all costs. waste of money.
