Sure its been disscused before, but for old times sakes, what kind of substrate (if any) does everyone use in their aquatic turtle tanks? do you vary the substrate with the type of turtle? just want to see all the different opinions
I really like the big river stones, they're flattish and like 2" in diameter. I want to get some more for when I set up their bigger permanent home; right now I only have enough to do about a 30G tank.
I use pebbles for my musk, and have used them for a lot of my turtles in the past. People mention turtles eating them and becoming impacted, but I have never known anyone personally who has had this happen. I got my rocks from the local creek, filtered out the really big ones with wire cloth, washed out most of the dirt and sand, and put it in the aquarium. It's as natural as natural can get.
