Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? Options for high turbidity

An old farm pond that has had livestock in and around it for years is going to be very fertile. Fertile water causes algae blooms. Algae blooms are the beginning of the food chain to support your fish population.

Like John F says, looks like healthy water to me. The swimmers you see are what feeds newly hatched fish after they have used up their yolk sac.

You may have a little bit excessive algae bloom from the fertility, but the aeration should help prevent some of the dangers of an unexpected bloom die off and O2 depletion.

Swimming pool clear water is not good water for raising fish. The algae you see making the water green are part of the food chain. The "swimmers" you see are also part of that beginning food chain.
