I've also got access to several plastic shipping pallets that have solid surfaces that I'm considering turning into bedding platforms. Putting a 3 inch edge around the sides, adding legs to two corners and placing them 2-3 feet deep so they rest relatively level and filling with peagravel. My available spawning area is pretty limited so I want to give them as much playground as I can.

Do you think the void created underneath would be too much of an ambush spot for any predators? The frey would be able to get into the grasses growing around the edge for a little cover. (Thats if we get some rain. Three weeks with no rain so the pond is down about 6 inches.)

.10 surface acre pond, 10.5 foot deep. SW LA. The epitome of a mutt pond. BG, LMB, GSF, RES, BH, Warmouth, Longear Sunfish, Gambusia,Mud Minnows, Crappie, and now shiners!!...I subscribe!!
