Q & A - Alternative Filter Installations - Kockney Koi
pond biofilter -- We're thinking of adding a small flock of ducks to the homestead for eggs and meat. With that comes the need for water. I'd love something a bit nicer and more natural than just a kiddie pool so building a small water feature is ideal.
