Manage the food intake of fish in the pond. Overfeeding will cause the fish to produce more waste, leading to lower water quality. Feed the fish only as much as they can eat in a few minutes, and be sure to clean out any eaten food after feeding. An automatic feeder is also an option for food management, but feeding by hand is recommended because it allows the feeder to keep a better eye on consumption and waste.

Hey, spammer... if it's lined it's a POOL, not a pond.
