Pond Boss Forums STOCKING A NEW POND Raising Forage and Bait Rasing GSH in above ground pools

So I was at a yard sale that had two 375 gallon ABS plastic tubs. Got them both for 50$ pretty good deal I thought. I was thinking about raising GSH to a large size so they could give my pond a good chance of a sustained GSH population. My thought is to drill a hole in the bottom of the tanks and install a 2inch bulkhead and install a overflow pipe. Put a pump in my pond and instead of adding a filter just keep a steady supply of pond water comming in the tanks. This should elimnate the need for a filter correct?
