Has anyone used Montmorillonite Clay? I know it's available in Dainichi food and in powdered form from TerraPond. I read a lot of great things about it and I was wondering if it would be a good addition to my ray and datnoid tank.
yeah, I guess it's the same old thing...if you need something like that, you're probably doing something wrong and there is no miracle substance to make your fish more healthy or everyone would be using it.
