I just recently bought some black diamond blasting sand for my 75 gal. After getting done with installation, I noticed that my synodotis looks like it has sand stuck in its belly. Is black diamond too Sharp for synodotis? What about geophagus?(I have one of those in my tank too, and they sift the sand through their gills) I can't find anything regarding it and I have heard of some blasting sands being too Sharp for fish like corydoras. Any help would be appreciated. Thanks.
