What size UV do I need for my pond ?
Before you purchase an Ultra Violet
You must first understand that you should have at least a hundred gallons more UV sterilization than actual pond water. This is because although the UV might say that it will work on a pond (lets say) 600 Gallons, if you pond was 550 gallons then the 600 gallon filter would be struggling to work flat out to keep it clean. You can never over do UV sterilization a pond - so make sure the UV you choose is adequate. If you intend to have a highly stocked Koi pond then you should aim to have a UV 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.
