Why Is My Pond Losing Water?
Pond water levels dropping is a common problem that many pond owners come across and can seem quite worrying. Everybody’s first thought is “I have a leak in my pond” and “there must be a rip”. However, only 5% of suspected leaks turn out to be leaking, so don’t panic just yet!
There are a few different reasons that could be causing the water levels to drop. We’re sharing 8 reasons your pond may be losing water, including how to diagnose and fix the problem.
Causing water levels to drop roughly 1 inch per week, evaporation is the most common cause of pond water loss. But don’t panic, this is normal. Factors such as location, time of year, pond size and especially weather, can affect the rate at which evaporation occurs. For example, high temperatures, sun exposure and wind can cause significant amounts of water to evaporate.
Evaporation can be reduced if the pond is shaded. However, unless your pond is located in an area where it can get shade, or you can add it, this may not be an option for you. Fortunately, water loss from evaporation is naturally replenished through rainfall.
If you take matters into your own hands and top up your pond water with a hosepipe, it’s important to do so little and often. This minimises the amount of chlorine entering the water if you can’t treat the tap water before adding it to your pond.
2 Tips for Adding Water to a Pond with a Hosepipe:
- – Rather than replenishing all the water in one go, try adding a small amount every day.
- – When adding the water, use the rose attachment on the hose to create a sprinkle rather than a pour.
Doing it this way ensures some of the chlorine will be burnt off before entering the water. However, if you must replace the pond water in one go, it’s essential to use Chlorine Klear to remove all of the chlorine from tap water. Then, add a dose of Pond Klear after topping up, this will help to replenish bacterial levels.
There are various factors around the edge of a pond that may cause it to lose water. Other than evaporation, low edges are one of the most common causes of water loss in ponds. This is when water escapes from the edge of a pond, typically at its lowest point. It’s also a sign that a pond’s edges are not level, explaining why water is being lost.
Similar to ‘low edges’ you must ensure pond liners are in a good position to contain water. For example, if a pond liner detaches from the edge, it may cause the water to escape. A simple fix for this is to simply pull and readjust the pond liner to lift the edge. Then secure its position using rocks or heavy ornaments.
Finally, consider what surrounds the edge of your pond. If your pond is surrounded by rocks (or other porous materials; such as wood) touching the water, they may absorb some water from the pond. If you have rocks which are partially submerged in the pond water, they are likely to increase water loss. This is because the thinner water will evaporate faster.
Depending on the location and nature of the pond, there may be a chance that wildlife is interfering with your pond water system and causing water loss. However, in most cases, it wouldn’t be water loss significant enough to notice. For example, birds may use your pond to bath and take residual water with them when they fly away. Water consumed by animals can contribute to water loss, and that includes your pets. However, again, it would not be a significant amount.
The least likely but the greater cause of water loss would be if wildlife was to damage or interfere with aspects of the water system. Factors like plumbing, filters or the pond liner. This is something you would become aware of if you check for leaks and damage in the pumps, plumbing and filters, as mentioned earlier.
