At least not if you want to have a pond with fish, plants and other living creatures. For those who cannot tolerate a single particle of algae along the side of the pond, or who cannot stand the usual seasonal changes of water clarity, we recommend that they get rid of their fish and plants, and that they regularly add bleach. If they want fish or water lilies, we suggest ones made of plastic. Having a live pond is like having children you learn to appreciate their core beauty and overlook dirt or untidiness around the edges. Having either too many fish or not enough filtration.
Many gardeners decide to have ponds in their backyards because they want to have fish.
The rest don't realize that fish are needed until after they have installed the pond. Putting too many fish in the pond, however, can be a disaster. It can seriously compromise the quality of water and place the lives of all of the fish in jeopardy. Too many fish can quickly foul the water, deplete the oxygen level, and change the ammonia levels to serious or even toxic. This is especially true in the middle of summer when pond temperatures rise during the day and drop at night.
