Evolution Aqua Pond Air Pump Airtech 75
Oxygen is vital to all aquatic inhabitants whether they are Koi, tropical / marine fish, goldfish or bacteria. It also stops stagnant areas which can cause poor conditions. This range was purposely developed for fishkeepers to deliver that essential element into their ponds – specifically air. This constant movement is also a good way to combat algae growth, especially in the summer months.
The Airtech collection is long lasting, durable, well engineered and robust. As standard, a weather tight, thermal protection device is built in to the unit to avoid overheating to prolong the performance and life of the unit. They are available in various formats, at rates of 70L/m to 150L/m to ensure a smooth, constant current in your pond.
