Now that summer has finally arrived we need to be aware of oxygen content in our pond water. The warmer the water the less oxygen it can hold! Every life form needs air to breath,to grow and to thrive! Fish,plants and wildlife etc consume a lot of oxygen,particularly in the summer months.Treating your pond or fish with chemicals can also dangerously deplete oxygen levels. We recommend using a pond air pump to sustain a healthy environment in warmer weather!
