I did, I still have yet to put the spawning structures in place. Next one I'll look into using pea gravel or a combination of the 2.
Yep, I did the exact same thing on the sand.
One of my daughters wanted some of the cute yellow bullheads from our creek in an aquarium tank. I put the sand from their original environment in their new tank. Now every time she does a water transfer, it stirs up a ton of fines in the tank.
P.S. Lots of good threads on Pond Boss for FHM spawning structures.
Good luck on your FHM project!
