Aquarium Safe Clay Plant Fertilizers 327899
Jan 28, 2018· Has anyone used Amaco terracotta air dry clay in their aquariums. I want to redo one of my tanks, taking out the gravel and adding an organic dirt, then top if off with maybe read that you could add red clay balls to the dirt and I have some osmocote plus that I want to roll into the balls. I was hoping the terracotta clay would work.
