Keeping koi in your garden is a very challenging task to do; hence one should know the important koi care tips. As you know, koi fish are insubstantial and it costs much time to provide them with the best koi care. Kois are a really specia carpe species and you can really make money of them. Here are some necessary tips to go by in taking care of your koi.

Feeding
Feeding is one of the most ignored tasks in keeping koi in the water garden. The righte choose of food is really important and it depends on the season. Although feeding is not entirely an issue to koi fish in a warmer climate, it is a big deal when you live in a Northern climate, where seasons change from summer to winter. The thing you need to check is when the temperature rises, the amount and rate of feeding koi should also rise.
When the temperature goes down to about 45 degrees Fahrenheit, kois go to hibernation. Therefore, you shouldn’t be feeding them with too much protein before hibernating, as this can cause infection, and infection during hibernation will mean adversity. So, before they go for a long slumber, change the food you feed them with low-protein source, preferably wheat germ based.
A very interesting fact about koi care is that they do not have stomachs. With this, they cannot store enough essential nutrients to keep themselves healthy. Although kois are known for getting their own food in the pond, such as insects and worms, it is also necessary to feed them with processed foods.
Keep in mind the amount of the food you are going to feed them. To do it, simply feed them with a calculated amount, and clock it for five minutes. After this time, you can see how much food has been eaten. If there are leftovers after five minutes, feed them in smaller amount the next.

Filtration
One special thing is, that you have a good and fully functional Koi Pond Filter-System. Bacteria, mud and algae free water is the key for a long life of your Koi fish. So protect them for these wastes. It is ensuring the fish’s safety as well as maintaining the pond’s cleanliness and the clarity of the water.
A koi filtration system of a pond has also other functions, such as protecting the pump from debris, eliminating biological wastes such as ammonia, getting rid of suspended particles before getting into the deep surface, taking care of dissolved wastes away from the water, and regulating the growth of algae.
Filter systems are classified by various types, so check out which one would be the most suitable for your pond to use.

Water Quality
Water quality is very important for koi to survive. Make sure to maintain its clear properties, for this is very crucial to the fish’s health. The ponds where koi are living are not just where they eat, sleep, and live. It is really important, to keep the koi pond as cleas as possible.
To determine how clean it is, try to look at the koi pond. If you cannot see the bottom of it, then it is not clean enough.
Also, try to determine the pH level and Nitrate level of the water using test water kits. If it is not in its balanced state, add some pond salt or baking soda on the water to put it back to its right rate.
