Filtering, Oxygenating and Circulating A pond pump filters, oxygenates and circulates water in the pond. This is a continuous process and should not be interrupted for any length of time in ponds with fish because the fish will suffocate without sufficient oxygen in the water. Garden pumps also filter debris from the water. If there is too much algae, much of it will be sucked into the pump’s filter where it remains until the pump is removed and the filter either cleaned or replaced. Submersible pumps are the most reliable and desirable because they are simple to install, require little actual plumbing and do not require priming.

This water is then pulled through a filter device, usually made of a netting material with tiny holes. This filter can be removed for cleaning or replaced. Once the water is filtered, it is jette
