With summertime temps reaching their peak in many places the past few weeks, it’s a good idea to make sure your pond isn’t becoming troublesome. Once the water temperature rises above 80 degrees, you could run into problems.
Do your fish appear stressed out, gasping for air close to the water’s surface or especially close to a fountain or waterfall? Warm water has a low capacity for holding oxygen, while cooler water can hold very large amounts of oxygen.
Warm pond water and increased activity go hand and hand, and that increased activity also means your fish require more oxygen when less oxygen is available, thus creating a vicious cycle. Stressed fish often begin to develop diseases, and soon enough you’ll have a domino effect.
Beat the Heat
There are some preventative measures you can take in order to keep your pond from becoming a warm, unhealthy mess. It all starts with a well-designed water feature. Depth, plant coverage, shade, and circulation should all be considered when building a pond. A minimum depth of two feet is suggested so the bottom can remain cooler.
You’ll also want to stock your pond with a lot of plants to provide shade for the fish. A good rule of thumb is to provide plant coverage of approximately 1/3 to 1/2 of the pond’s surface area.
Perhaps one of the most important parts of pond design is circulation. If possible, you’ll want to place your biological filter and mechanical filter across the pond from each other, so that all areas of the pond are skimmed and the water circulated. And keep in mind that waterfalls, streams, and even fountains play a huge part in the oxygenation of the water in your pond.
During the hot summer months, you can use some of these tips to help keep your pond performing optimally:
- Add oxygen to your pond by placing an aerator or AquaForce® pump in your pond. You can also install a fountain with a pump if your pond doesn’t have a waterfall or stream built in.
- If you feed your fish, feed them in the morning and be careful not to overfeed. Uneaten food decays faster in warmer water and can pollute the pond.
- Be sure to remove dying leaves and flowers before they have a chance to decay in the warmer water.
The bottom line is that you need to keep an eye on your pond and let your fish and plants do the talking. If you have a balanced ecosystem, you don’t need to be checking your pond out everyday, but you do need to check it out every once in a while to make sure your plant and fish friends are healthy.
