I do want a bass pond. The spheres look perfect for a liner.I do see baby fish several times a year ,some are bass and some are goldfish. A couple of the bass will come up to the dock and eat bread with the gold fish.(so they are probably starving). there are 4 or 5 large rocks ,200 lbs'ers in the bottom, some silt,and a little sand. the rocks around the outside are about 1.5 feet under water and they are head to basketball size. Thanks so much for the tips, keep'em comming.
