Summer Pond TipsBrett Fogle Use an oxygen tester and air stones to keep your available oxygen level to at least 7.0 parts per million of dissolved oxygen in 90 degree F. water. Koi and goldfish start showing signs of stress at oxygen levels of 4.0 ppm and will start dying at 3.0 ppm. The higher the water temperature goes the less oxygen thats available. Water temperatures over 90 degrees will also affect fish health so keep the temperature under control by providing shade during the hottest parts of the day. Its Parasite Season Warm water causes an increase in parasites such as anchor worms, fish lice or flukes. Some parasites such as anchor worm and fish lice are visible and can be treated with Dylox, Dipterex or Masoten. Invisible parasites such as external protozoa and flukes can not be seen but they usually cause symptoms including extra thick mucus, constant scratching by rubbing against objects, flashing, or jumping. Some variations will cause a noticeable head shaking and yawning. COntact your pond specialist for treatments because different symptoms are indicative of different infections. Follow label instructions at all times or you could cause serious injury or death to your fish. Summer Koi Feeding Tips If you water is between 70 to 85 F. then feed a low protein food in a quantity that is equal to 1.0% to 1.5% of total koi body weight in pond. Estimate total koi body weight in pond and feed recommended % of food daily based on season and water temperature divided into intervals of about 2-2-1/2 hours. It takes koi about 2- 2-1/2 to digest food in warmer water and 4-8 hrs in colder water when feeding is begun. So in warmer ideal water temperatures feed 5-8 times daily the individual portions totaling daily amount needed. In cooler temperatures feed 1-3 times daily. Sunblock for your Koi Koi are not immune from sunburn, especially in shallow ponds that get direct sunlight. Provide shade such as water lilies or a rock overhang. Even a beach umbrella will do in a pinch. Watch for Evaporation Depending upon the surface area of your pond, you can lose several inches per day to evaporation. Monitor and adjust your water levels daily or as neccessary. Remember, do not use water with chlorine in it if you have fish! Five Quick Tips For Healthy Summertime Water
