Summer Pond Tips
by: Brett 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 that's 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.
It's 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
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:
1. Ensure that you have good mechanical and biological filtration and
that your pump will turn the pond water over totally at least twice per day.
2. Operate the pump 24 hours a day.
3. Provide adequate shade by having 60 to 70% of the pond's surface
area covered with floating plants or other types of shade.
4. Add water clarifiers and bottled bacteria if your water remains
cloudy even when good filtration is present.
5. Test oxygen levels daily and add air stones if levels fall below 7
