Ideal for creating water features, pond circulation, waterfalls, fountain streams and marine aquariums. This submersible pump is suitable for both fresh water and marine aquariums approximately 5000L in size. It is designed for low energy consumption and includes 4 nozzles with an adjustable flow rate (additional nozzles and flex tubes available for purchase in store) that operate in near silence to create the optimal environment for your fish and water creatures by controlling circulation and increasing oxygen levels. The sponge filter forms a barrier that captures larger particulate matter before it enters the water feature and clogs the canister. It prevents debris from circulating your pond and maintains a clean, clear and healthy environment. This high performing, long operational life, submersible pump comes with a 1 year warranty (does not include impeller in warranty).
