Manage and track your koi!

With many koi in the pond, it's easy to lose track. With KoiControl you won't! You can save all important information about your fish, such as name, variety, age, size, weight and much more. Additionally, you can track the growth of your fish exactly and thus make your success measurable.

Determine the ideal amount of food!

How much food do your koi need to grow ideally? Our integrated food calculator provides you with the answer. Based on your koi population and the water temperature, our food calculator automatically calculates the recommended amount of food for your growth ambitions. You don't even need to know the weight of your koi. KoiControl can determine the weight very accurately based on the length of the fish.

Calculate the correct amount of salt for treatments!

Salt is a popular tool for treating koi diseases, as it is both cheap and effective against some parasites or algae. However, meticulous care must be taken to achieve the correct concentration. With the salt calculator you can calculate the correct dosage for each of your managed ponds without errors and without calculators.
