Summer Koi Keeping tips:

  • Now that the water temperature is above 60, you should be feeding a high protein food with color enhancers, and stabilized vitamin C (we recommend Dainichi Premuim) Once temperature drops below 60 switch back to all season wheat germ food. Small feedings a few times a day is better then one large feeding, since koi do not have a stomach and cannot store food. Koi are grazers and are always looking for food.
  • Test weekly, fully mature filters should be keeping Ammonia, & Nitrite at zero. PH should be between 7 - 8.5. Total alkalinity is best over 100 PPM, this feeds your bacteria in the filter and stabilizes the pH of the water.
  • Clean your filter weekly, if you have to clean pads or balls, be sure not to use chlorinated water as it will kill your active bacteria that you have worked so hard to develop. Clean media in a bucket of pond water or well water.
  • Verify that UV lights are working, you should see the ends glowing at night. If your water is green your UV is not working.
  • Monitor your fish for any unusual behavior, like flashing, jumping, or hanging on the bottom with clamped fins, all are signs that there may be a problem.
  • Continue to add microbe lift bacteria, and KoiZyme to keep a healthy enviornment. Test, test, test.....or the only way you will know there is a problem is when your fish tell you!
  • Oxygen is the foundation of life in your pond and you should supplement passive gas exchange. Gas exchange (oxygen, hydrogen sulfide & ammonia) takes place at the water gas interface. Waterfalls and fountains do facilitate gas exchange but can't compare to the efficiency of small bubbles containing a huge surface area.
  • Water should be circulated from the deepest part of the pond to help break down organic materials during the summer. Warm water cannot absorb as much oxygen as cooler water, which is why aeration is so important during the hot days of summer.
  • Oxygenating (submerged plants such as anacharis) plants are a mixed blessing because they produce oxygen during the daylight hours but consume oxygen at night.
  • The most efficient method of aeration is the installation of an external air pump connected to an appropriate diffuser. Ceramic air stones connected to a external air pump designed for outdoor use are the best choices for summer and winter use.
