Nessus asked: We recently bought a house with a small outdoor concrete pond. We were told by the previous owners at closing that they used to keep fish in the pond.
It looks like it holds around 60 - 80 gallons of water. There is a drain hole right in the center, but there is no pump or filter. It hasn’t held fish for a some time since the sellers had rented the house for a few years before selling.
What do we need to do to turn this into a fish pond? I’m willing to tackle almost any DIY project, but I would prefer not to have to dig up my yard if it can be avoided.
