What is Effective Volume ?
The effective volume is the quantity of water in your pond, plus an allowance for shallow and or ponds exposed to high levels of sunlight. Both of these situations will result in a higher than normal algae growth, and fish pollution. We advise that to ensure your that your equipment is correctly sized, the effective volume be considered the minimum size for the equipment you select. However do remember to check the details of the product you are interested in, to ensure that there are no other allowances or consideration specific to that product are required.
