Yes, filters help minimize maintenance for the owner. There are two types of filters recommended for the water garden.
1. A pump filter to protect and hide the pump while removing dirt and debris from the surface.
2. A pond filter helps in keeping the water safe for plants and fish.
What kind of filter is going to be the best for my pond?
This is a question that will have to be answered a little bit more extensively as this largely depends on what type of pond you have or planning to have. The question you have to ask yourself is: “Do I plan on stocking my pond with ornamental plants or ornamental plants with fish”?
The following should give you a better understanding of the different types and functions of filtration products available:
• Pump Filter – If your pond solely contains ornamental plants or if you are looking for a pre-filter for your pump, then the mechanical filter is what you most likely will need. Its primary function is to separate large particles and debris while also protecting the pump.
• Pond Filters – If you are going to incorporate fish into your pond and want to provide a safe healthy environment, then a biological filter is one of the best options you can use. These filters allow beneficial bacteria to gather and colonize which in turn help convert toxic nitrites into helpful nitrates. These nitrates are then used by plants. Biological filters typically clean the water using mechanical filtration as well as removing toxins from the water. They are very popular as being the sole filtration source because they serve both purposes.
