As temperatures rise, dissolved oxygen levels in your pond progressively fall. The increased temperatures and influx in organic nutrients encourage plant and algae growth, reducing oxygen levels and impacting the efficiency of beneficial bacteria in your pond. If oxygen levels become too low it can make fish susceptible to stress and disease, an indicator of this will be fish regularly gasping at the surface for air. Therefore, the incoming summer period could be daunting can be daunting if your pond is not receiving enough oxygen to share between all its inhabitants. Fortunately at DU Waterscapes we ensure any pond created with the intention of holding fish has a waterfall or stream system incorporated into it. This guarantees that there is a consistent supply of dissolved oxygen into your pond’s ecosystem, allowing beneficial bacteria to function properly, reducing stress levels on fish and inhibiting algal blooms.
