A: Baby, it certainly is hot outside! As the temperatures rise, you might think the coolest place to be is in the pond with your fish. Surprisingly, however, pond fish can feel the heat, too. The warm water feels “stuffy” to them because it contains less oxygen than cooler water. Check out these four tips for keeping your koi and goldfish cool as finned cucumbers.
1. Check your Water Temperature: Ideally, your pond’s water temperature should be at a comfortable 70 degrees Fahrenheit or less. Use the Pond Logic® Floating Pond Thermometer to check the pond’s temp, and if it’s too warm, do a partial water change to give the fish some fresh, cool water.
2. Top Off the Pond: Even if your pond’s water temperature is hovering near that 70 degree zone, it’s a good idea to keep an eye on your pond’s water level and add more when needed. When the mercury rises, remember that your water will evaporate more quickly into the atmosphere.
3. Create Shady Spots: Just as you seek out shady spots to shield yourself from the sun’s rays, fish will do the same to keep themselves cool – and prevent themselves from getting sunburned! Be sure to provide floating plants, water lilies and other types of shade cover for your pond pets. Have fun with it! Add some tropical lilies like the Panama Pacific, tropical bog plants like the Red Canna or other hot-weather plants that prefer the warmer weather.
4. Provide Aeration: Do you like sitting by the fan or swamp cooler during heat waves like this one? Well, an underwater bubbler or aeration system, such as the Pond Logic® PondAir™ Aeration System, is like a fan to fish. The cooler water that’s loaded with oxygen is easier for the fish to breathe.
While the heat waves persist this summer, follow these tips to ensure your fish stay cool and comfortable in their watery home. They’ll thank you for it!
