Neither need a substrate, unless your bluegills spawn, but if they do, most likely everything will be dead anyway. Mean little buggers when they get "the urge". Kinda like certain women I know.........
Anyway's, you would probably enjoy the pond more if you had some dark brown gravel. you would be able to see the fish alot better, and the gravel wouldn't get sucked into your filter. Have you thought of plants? A couple of lillies would be cool, just hang a shoplight over the pond.
