Place the pump at one end of the pond and the discharge tube at the other. This will prevent stagnation and aid in keeping the pond water clean. There are obviously many other situations and combinations that can come up in a water garden, making a choice of pump size and type more complicated. We here at Merrifield Garden Center will be happy to assist you in choosing the right pump or pumps for your unique situation. We do ask that you help us by knowing either your water volume or the approximate dimension of your pond.
Every water garden is enjoyed much more if the water is clean and clear.
Often, through having the proper amount of sun, plants and fish, the pond water will be clean and clear. Biological filters help nature eliminate toxins in the water, such as ammonia. These toxins naturally occur in ponds from fish waste, decaying organic matter and excess fish food. When these toxins build up, they can be harmful to plants and fatal to fish. Biological filters use naturally occurring bacteria to break down these toxins into safe compounds, making the water clean.
