What size filter do I need for my pond ?
Before you purchase a pond filter
You must first understand that you should have at least a hundred gallons more filtration than actual pond water. This is because although the filter might say that it will work on a pond (lets say) 1300 Gallons, if you pond was 1275 gallons then the 1300 gallon filter would be struggling to work flat out to keep it clean. You can never over filter a pond - so make sure the filter you choose is adequate. If you intend to have a highly stocked Koi pond then you should aim to have a filter to cope with one and a half times the capacity of the water in your pond.
To calculate the capacity of your pond, enter the AVERAGE measurement in the boxes below.
Please enter FEET for GALLONS or CM for LITRES.
