With temperatures rising and the Summer Solstice passed, you may be spending more time enjoying your outside space. And if you have a pond, you’ll know that some maintenance tasks are vital to ensure your pond is looking it’s best in the sun!
Here we have rounded up our top 10 tips for looking after your pond during these Summer months:
1. The Sun/Shade Balance
Whilst trees do offer benefits for any pond they are growing near to, providing valuable shade and shelter for wildlife, too much shade can reduce the growth of pond plants, and conversely, too much direct sunlight can cause algae problems. Large quantities of fallen leaves can also lead to an increase in decaying organic matter in the pond and affect water quality. It is best to create a balance of both sunny and shady areas, so prune trees where necessary and look at utilising many of the broad-leaved pond plants to create welcome shady areas for the pond's inhabitants.
2. Beware of Poisonous Garden Plants
When creating a new pond, bear in mind that some trees and plants are poisonous. For instance, avoid positioning the pond anywhere near laburnum, laurel, wisteria, or yew. When planting around the pond, be sure to check on each plant's suitability as many varieties such as delphinium, foxglove, ivy, and
3. Grow a Mixture of Different Pond Plants
Plants not only make the pond more aesthetically pleasing, but they also generate hiding places within the pond, create shady areas, and absorb nitrate, helping with water quality. Additionally, they assist in oxygenating the water and provide spawning/breeding sites for fish and other wildlife. Try to provide a mix of plants, such as submerged pond plants/oxygenators, marginal vegetation (which will provide refuge for amphibians, dragonflies etc), floating species, and for deeper ponds, water lilies.
4. Avoid Tap Water
Although tap water in the UK is treated to a high standard, it still often contains high levels of nutrients such as nitrate and phosphate, which contribute to algae problems/green water within the pond. Tap water also contains chlorine/chloramine, which, although making the water safe for us to drink, is very harmful to fish. When topping up the pond, it is best to use rainwater collected in a water butt. If
5. Be Careful With Chemicals
Take extra care when using pesticides, herbicides, or fertilisers near a pond, as these can easily enter the water through run-off when there is rain, or if a sprayer is being used. The average sized pond will not be able to dilute such chemicals to safe levels, and they could have a disastrous impact on the pond life.
6. Oxygenate Your Pond
A healthy pond will be well oxygenated, a necessity for the survival of the fish, amphibians, plants, and other organisms within. Oxygen is also essential in the breakdown of decaying organic matter. Ponds that lack oxygen will quickly become stagnant, often smelling unpleasant, with a thick layer of algae soon developing (which will further deplete oxygen). Oxygen levels can be maintained via pond pumps, filter outlets, air pumps/airstones, fountains, and waterfalls. Wherever the surface water of the pond is
7. Keeping Green Water At Bay
Remember to change the bulb in your UV clarifier unit every 6-12 months.
8. Regular Filter Maintenance
If you have an ornamental fish pond, it goes without saying that regular filter maintenance is of great importance. A well optimised and maintained filter should only need cleaning a few times per year - the amount of cleaning depending largely on your pond's bio-load. In general, filtration should be cleaned as soon as you notice a drop in water flow from the filter outlet pipe, as this would suggest that the mechanical filter media is starting to become clogged with debris. Sponges should only ever be rinsed in a bucket of water taken from the pond, in order to preserve the beneficial bacteria that break down the fish waste (chlorine and chloramine in tap water will kill this essential bacteria). Biological media should not require cleaning as often, but when it does, again, a quick rinse in aged pond water is all that is needed. Aside from the impellor, nothing inside the filter needs to be spotlessly clean.
9. Test the Water Pond fish produce waste in the form of ammonia, which is then broken down via the filter bacteria into nitrite. Both ammonia and nitrite are highly toxic to aquatic life, which is why it is important to have a decent filtration system in place. Nitrite is then converted by the filter bacteria into less harmful nitrate, which is subsequently either taken up by plants or diluted via small water changes. These levels can all be monitored using a simple test kit, which only takes minutes to use. High levels of nitrate, and also phosphate (present in fish food, soil, tap water), can both cause algae blooms and simple testing can alert you to rising levels and necessary action can be taken.
10. Don't Overdo Things Finally: don't overstock, don't overfeed, don't
