Summer Pond Tips

Low Oxygen levels Kill Fish

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 hours.

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 necessary. 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 PPM.
