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

I put this in my aquarium hoping for clean water like he said but since I added it two of my turtles have died a few days apart. I've had these turtles for months and never had a problem until I put this cube in them. This was the only new thing I added to the tank, so I'm guessing what's in this product is slowly killing our turtles. My kids are devastated. It breaks down in the water, and even changing it immediately turns dirty and dark from the debris hiding in the gravel. I will never order these again.
