Koi Education and Koi Keeping Basics

These multi-colored fish are simply beautiful, but koi also require very high water quality to thrive in a pond or aquarium. That’s where Pentair Aquatic Eco-Systems can help.

Koi Education Basics

Clean Water

The Cleaner the Water, the Healthier Your Fish

The first thing to know before buying that first koi is that filtration is essential. Don’t cut corners. Carefully plan for the size of your pond and the number of fish that will live in it. No filtration or inadequate filtration will make your koi sick from the waste they leave in the water. Our experts are ready to help you select the biological, mechanical or chemical filtration equipment that will keep your fish healthy.

Temperature and Chemistry

Koi are Sensitive to Temperature and Water Chemistry

You also must carefully manage your pond’s temperature, water clarity, dissolved oxygen levels and other parameters including ammonia and nitrite, along with algae and pH levels. Again, count on our biologists and technicians to provide the information and advice you need. Pentair Aquatic Eco-Systems™ offers a complete line of test kits, filtration and disinfecting equipment to ensure a proper water environment for your fish and plants.

Food for Koi

What Do Koi Eat?

You’ll need to feed your koi twice a day. We offer a selection of foods from Blackwater Creek, Hikari and Zeigler to aid in growth, color and fish health. Automatic feeders allow feedings to be tailored to the biological clock of each species. Implementing a schedule throughout the day may help reduce size variance of the fish, improve feed conversion ratios and level the load on your filtration system.

Grow a Business

From Hobby to Hatchery

Many koi lovers want to make the move from raising the fish for personal enjoyment to running a business that sells koi to other hobbyists. Our supplies include graders, pumps, hatching jars, trays, troughs and shipping bags. Our experts can provide you with insights and scientific information to help you grow your business. They can also recommend equipment and supplies, such as brushes commonly used in koi ponds to encourage fish to spawn.

Cold-Weather Care

Keeping Your Koi Thriving in Cold Weather

Koi can live in ice-covered ponds, but will die if the ice cover lasts too long. To prevent a fish-kill, keep a small percentage of the surface ice-free for gases to naturally enter and leave the water. Also, water temperatures below 65°F (18°C) can stress fish, reducing their resistance to disease. Rapid and extreme fluctuations can also cause disease. Use one or more small heaters with thermostats built for the purpose.
