Review on 🐟 Educatmon Eco-Aquarium Water Purifier Cube - Enhanced Filtration & Absorption for Aquariums, Ponds, Fish Tanks, Water Tanks, Water Purification by Keisha Smith

Not even worth the one star I gave it. I have read in previous reviews that it is damaged but mine arrived undamaged so I put it in the tank under the filter as per the packaging. It was to last 6 months with purges in between. After two weeks I cleaned the goldfish tank and the cube fell apart. There was no flush. It was torn into many pieces, coloring everything it touched black with charcoal. Made a mess in my sink. Revain wants to return it, it will be fun and no return label will be printed. Biggest junk. And what a hassle. My carbon in my filter worked better than this one.
