Pond Filters & UV
Why You Need Filtration
A biological filter is the most common way of keeping a fish pond clean and healthy for your fish. Ponds without filters are usually green and not pleasing to the eye. Itis possible to create a clear pond with the use of waterplants which add oxygen to the water, however most pond owners find this system unsuccessful and have problems with plants removing oxygen from the water during night time hours. A biological filter is the way to solve the green water problem.
