Bottom drains are drains located in the bottom of the pond that remove all the dirt and debris such as leaves and fish waste from the pond. Some lead to a filter that deposits the grime into a separate compartment, whilst pumping clean water back into the pond.
They are relatively easy to install and can really make a difference to the clarity of your pond. Whatever the size pond you have, you’ll find that a bottom drain can help you to maintain a healthy, clean pond all year round.
