What is this pond fish food?

This pond fish food, made by industry experts NT Labs, is a specially formulated Koi food. It's packed with essential nutrients, vitamins, minerals, and trace elements that promote natural biological functions, as well as improve growth, colouration, gut health, and immune systems in your pond fish.

Only the finest quality ingredients go into this Koi food. These ingredients create a highly palatable and digestible food that both young Koi and adult Koi love. This pond fish food also contains a prebiotic (fructo-oligosaccharide) that supports the probiotic bacteria living inside your Koi's gut.

These Medikoi Probiotic pellets have been vacuum-coated to prevent the proteins and oils in the pond fish food from leaching into your pond water and causing an unsightly surface slick to form. This is great as it keeps both your fish healthy and your pond healthy.

What are the benefits of this food?

This Medikoi Probiotic has many different benefits, especially for Koi. Here are some of the changes you may see in your Koi in your garden pond after you start feeding this pond fish food:

  • Healthy growth - this Koi food has high protein (over 38%) and other essential nutrients that promote growth and good body shape.
  • Enhanced colouration - this is a colour enhancing food that, thanks to the inclusion of spirulina and astaxanthin, boosts your Koi's natural pigmentation.
  • Improved gut health and immune system - a combination of probiotic bacteria and a prebiotic improves digestion and helps your Koi get all the essential nutrients out of their food.
  • Cleaner water - this pond food is very digestible, meaning nutrients are fully digested rather than passed back into your pond where they'll pollute it and promote algae growth.

When can I feed this food?

Thanks to the nutritional composition of this Koi food, it's suitable to be fed all year round. It can also be fed over a large water temperature range, 5°C to 26°C, making it a great choice of pond fish food in climates where weather can change quite dramatically between seasons.

The abundance of vitamins and additives in Medikoi Probiotic will help keep your fish healthy year round and whatever the weater, and the inclusion of probiotic bacteria ensures maximum uptake of nutrients by your fish, even in lower temperatures.

As temperatures drop below 5°C, we recommend supplementing your fishes' diets with some high-fibre wheatgerm pond fish food. These pond sticks, along with the probiotic and prebiotic elements of Medikoi Probiotic, will aid their digestive systems during winter when they go into a dormant state, similar to hibernation.

How do I feed this food?

This Koi food should be fed twice daily and only a quantity that your fish can consume in around 10 minutes. Do not overfeed, and be sure to keep your pellets sealed in their original packaging and stored in a cool, dry place away from direct sunlight.

This Medikoi Probiotic from NT Labs is available in a wide variety of sizes, giving you the choice of testing the pond fish food out with a small, 750g bag, or stocking up for an entire pond season with a 10kg tub. Just use the dropdown menu above to select the right size for you, the pond owner.
