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

I bought this item which says it was a 600g pack and I made sure to order the 600g item and after I got my removed old resin and went to order, to my surprise, I refilled the container, it wasn't enough! I then removed the label that Revain puts on the products saying it's a 600g pack to find out the actual weight is only 500g as stated on the manufacturer's label and not enough to fill a standard 10 inch tube in the image I've added. Not happy at all. I told Amazon customer service to make changes to the system so no one else had this issue and it sounded like they definitely didn't care.
