When pond owners observe a decline in water levels, they frequently become concerned. Although it is tempting to believe that the pond may be leaking, mechanical problems or natural processes are more likely to be at blame.
Let us explore common reasons for water loss and how to fix them by taking help of That Pond Guy, a pond specialist available in the UK.
1. Evaporation
Evaporation is common, especially in summer, as heat and wind increase water loss. Factors include weather, pond size, and sunlight exposure.
How to reduce evaporation
To help minimize evaporation, try providing shade over the pond. Adding floating plants or lilies can offer protection and other benefits, such as improving water quality. Natural rainfall will frequently raise the water level if you are unable to provide shade.
When adding tap water to your pond, exercise caution because chlorine can kill your fish. Before adding chlorine to your pond, neutralize it using a pond water conditioner.
2. Pond Plants
Aquatic plants like water lilies and land-based plants, such as trees, can absorb water, contributing to pond water loss.
How to manage plant-related water loss
To lessen the quantity of water they absorb, it is recommended to prune any trees or plants that hang over the pond. However, the advantages of plants—like lowering evaporation by providing shade and enhancing the appearance of ponds—often outweigh the water they use.
3. Water Features
Waterfalls, fountains, and features can cause water loss through splashing and evaporation, especially when increasing surface area exposure.
How to minimize water loss from features
To return water to the pond, make sure your water feature is positioned properly. To lessen splashing, change the flow rate if needed.
4. Leaks in Equipment and Plumbing
Leaks in pond equipment, like pumps or filters, can cause water loss and should be regularly checked.
How to check for leaks
Inspect all connections, pipes, and the filter for cracks or leaks. If you notice any, replace the damaged parts promptly to prevent further water loss.
5. Pond Liner Damage
Water loss may result from a pond liner tear or break. The liner can be the cause if the water level falls noticeably.
How to find and repair a leak
Switch off the pump and monitor the water level. Once it stabilizes, carefully inspect the liner for visible damage. A milk test, which involves adding a glass of milk to the water, can be used to identify the leak’s location and facilitate patch kit repair.
6. Wildlife
Wildlife, birds, and other animals may come to your pond to drink or take a bath, which will lead to loss of water. This does not cause big loss of water most often, but it is gradual, and it can build up.
How to manage wildlife water loss
You can, however, minimize animals getting close to the pond by building barriers or using nets around the pond area. By understanding these usual causes of water loss, you can ensure that your pond stays healthy and that the water levels remain constant throughout the year.
