The importance of good pond water quality is not lost on most pond owners. However, understanding how to achieve and maintain water quality can prove to be a challenge for even the most avid water gardeners. The water may be perfectly clear, but several factors may indicate that conditions may not be ideal. Before you decide on a treatment plan for your pond’s water, consider the following questions:
Are there too many fish in the pond?
10 fish for every 100 gallons of water is the absolute maximum. If there are too many fish, consider finding some of them a new home. Better yet, build a second pond for the overflow.
Are the fish overfed?
Excess, or leftover food can affect water quality. Feed the fish no more than once per day, and no more than they can eat in 2 to 3 minutes – then remove all remaining food from the water.
Are there too many plants?
Too many plants can cause oxygen deficiencies at night due to the photosynthetic process, where the plants take in oxygen and give off carbon dioxide. Ensure that no more than 40% to 60% of the surface area of the pond is either covered or shaded by plants.
Is the pump size affecting water quality?
The entire pond’s volume should be circulated, or turned over a minimum of once every hour. Ensure that the pump’s flow isn’t restricted by any debris, or that it isn’t exceeding its flow limitations. Refer to the side of the original packaging for specifications.
Is the correct filter in place?
Most manufacturers rate their filters based on the amount of water in the water feature. If the filter is too small, it will be less effective at removing debris and fish waste. Always use a filter rated higher than necessary in order to guarantee effectiveness, and be sure to clean it at least once per year, as well.
Is the temperature too high?
Direct sunlight, or inadequate circulation of pond water can lead to higher temperatures. Water exceeding 75º F has a more difficult time retaining acceptable levels of dissolved oxygen, and can promote algal blooms. Again, ensure that no more than 40% to 60% of the surface area is shaded, though.
