yeah during summer the pond gets pretty weedy but not what i would consider extreme. i've been hesitent to stock bluegills because i figured they would outcompete the yellow perch and my perch would die off. i'm guessing without adding bluegill my only real option is to remove quite a few bass from the pond. i've tryed adding shiners but the tiny bass wipe them out in no time at all no matter how many i put in at once.
