Your pond will be perpetually "muddy" cloudy once the cats get 12"-15". However you should not be bothered with mat or string algae. Don't expect your bass to grow much beyond 12" until you thin them out. Then your water may be too murky for the bass to adequately see their food and catch it. Thus still poor or slow bass growth.
