Why do you want to put gravel down? The bluegill have already made great nests on the available substrate. I don't know why you'd want to spend more money on something that's being done for free.
Cuz I don no nuttin 'bout nuttin so I'm askin'.
I saw a post about putting gravel down for bluegill nests and I thought maybe I was supposed to put gravel in there... You all know I don no nuttin bout nuttin...
Thanks
