What You Shouldn’t Do on Hot Days!
-
Don’t Overfeed Your Koi
Koi eat less in extreme heat, and uneaten food quickly decays, depleting oxygen and raising ammonia levels. Feed lightly — or skip feeding altogether — during the hottest parts of the day.
-
Don’t Perform Large, Sudden Water Changes
Adding a lot of cold water can shock your koi due to the sudden temperature difference. If you need to cool things down, do small (10–20%) changes gradually with dechlorinated water.
-
Don’t Use Chemicals or Algaecides
Treatments that kill algae or bacteria use up oxygen as they work, which can worsen oxygen depletion and stress your fish. Stick to natural shading and aeration instead.
-
Don’t Turn Off Aeration or Water Features at Night
Oxygen levels drop most during warm nights when plants and algae also consume oxygen. Keep pumps, waterfalls, and air stones running 24/7 in hot weather.
-
Don’t Ignore Shade and Shelter
Direct sunlight rapidly heats shallow water and can cause burns or overheating. Always provide shaded areas with plants, covers, or shade cloths.
-
Don’t Panic and Add Ice or Ice Blocks
Sudden cooling from ice can cause temperature shock and harm your koi. Instead, rely on gradual cooling with shaded water changes or aeration.
By avoiding these common mistakes, you’ll keep your koi safer and your pond ecosystem stable, even during the most intense heat.
