I can't believe what I saw today at Petsmart. We all know that small stones/rocks and gravel can cause serious problems. Well it seems some companies will do anything to make a buck. They are now selling something called Total Turtle Aquatic Substrate.
I didn't find it on their site but you can find it at drsfostersmith.com. It appears to be simple gravel and a few packets that say they are beneficial bacteria and such. I mean really do they want to cause problems for the turtles? Or maybe I'm wrong and its not rocks but a dense mineral that dissolves over a long time and digests.
