Mot states have guidelines on fresh water fish consumption. The general rule is, the higher up the food chain, the less of that fish you should eat. I manage my water in the most natural way I possibly can to ensure the fish are safe to eat and the water safe to drink, literally.
What you put in your pond ends up in your fish, one way or another. How much copper sulfate, alum, glyphosate...etc do you put into your pond and eventually your fish?
What do you feed your fish? They are what they eat. How safe is that mass produced food Purina makes for the species further up the food chain, namely you?
