Bubbler kits pair an outdoor air pump with weighted airline and one or more diffusers on the pond floor. They run all year on 4 to 100 watts, add oxygen at the bottom where fish waste collects, and keep a patch of ice open in winter. Check how many diffusers come in the box: a single small pump spread over two diffusers gives each one less air.
