Substrate Question

  • We are currently upgrading MFK. thanks! -neo
Looks kind of large and maybe a little sharp, hard to say though from the pictures.
 
I had black gravel in my tank that looked just like that. Mine was sold by estes. I am now a bare bottom fan but would definitely do gravel verses sand.
 
I agree that that gravel looks a bit sharp. Not sure of the availability of estes or 3M down there but those two are used with rays all the time.
