Mel's in charge of the invasive species department in DFO for the next month so, yeah.If that pond has any drainage away it would be bad to have goldfish that might invade somewhere they aren’t supposed to be.
She's well aware of how many we already have on the property

This setup will either be inside the house or on the deck, a lot of people run these systems off a small fish tank. Keeps the nutrients in the water and helps balance things supposedly.
Haven't decided on that yet, this was kindof a spur of the moment purchase, something to mess around with, so she's still in the reading up stage.
The pond version will be quite different. Floating with a small solar pump probably.
