Pond brings beauty, variations of species, and peacefulness on the garden, and at the same time comes with problems such as evaporation and algae. Your pond will be healthy and colourful year-round if you know common issues that occur and how to correct them.

Common Pond Issues and Solutions
1. Too Much Duckweed
Duckweed often invades ponds due to ducks or external sources, and excess chemicals or nutrients. To control it, scrape it off with a board or sieve weekly. Introducing oxygenating plants will help shade the weed and prevent growth.
2. Blanketweed Growth
Blanketweed thrives in small ponds with high nutrient levels, especially in spring. To remove it, rake the weed out and return any creatures to the pond. Let the weed sit on the edge for 48 hours before composting it.
3. Green Water
Green water is caused by algal blooms, often in new ponds or after pollution. To address it, stabilize the pond naturally. Barley straw or willow stems may help, but avoid chemicals that could harm essential microscopic algae grazers.
4. Brown Water
Brown water is caused by low oxygen and high nutrient levels. Introduce oxygenating plants like yellow and white-water lilies to restore balance and improve water quality. Without adequate oxygen, your pond’s ecosystem may struggle to support wildlife.
5. Punctured Liner
A punctured pond liner can occur from sharp stones, roots, or even pets. Repair kits are available at garden centres, but if repairing is not possible, consider converting the pond into a bog area and building a new one nearby.
6. Grass and Leaves
Water pollution can result from grass and leaves blowing into the pond from overhanging trees and shrubs. Debris can be efficiently captured and kept from contaminating the water by erecting a border of tall grass or other vegetation around the pond.
7. Frozen Pond
Frozen ponds are common in colder temperatures. To prevent freezing, float a ball on the surface overnight to keep water oxygenated. If frozen, clear snow to allow sunlight through. Avoid breaking the ice, as shock waves can harm pond life.
Summer Pond Problems
During the summer, ponds tend to thrive with minimal maintenance.
However, some specific problems can arise, such as:
1. Water Loss
Due to evaporation, particularly in hot weather, add water regularly to compensate for losses.
2. Fish Gasping for Air
Oxygen levels drop in hot, still water, particularly in ponds with dense plant growth. Ensure water features like fountains or waterfalls run throughout the night to oxygenate the water.
3. Excessive Plant Growth
During warm months, fast-growing plants may choke the pond. Remove excess plants to maintain balance and prevent overcrowding.
4. Algae Growth
Green water and blanketweed can become problematic. It is critical to add more aquatic plants and decrease water nutrient levels if you observe an increase in algae in order to preserve equilibrium.
You can reduce these typical problems and maintain the health of your pond by keeping an eye on it and keeping its equilibrium.
