Hello, the koi's i have in the pond are not big they are about 3 to 4
inches in length. the thing i hate the most is i have a water bell
fountain and the water is green that comes out of it, it just looks
terrible and my pond is preformed plastic
i just thought if i had plants in the pond i would promote more algae i
bought a pond kit that comes with pond blocks and 3 bottles of liquid
and nothing has helped i just figured i wasn't filtering it enough
