As an owner of a Koi pond, your priority should be to keep your pond in good condition. Keep in mind that prevention is always better than cure: so once your pond starts to have some problems, it will really take more money and time on your part to fix these.

No overfeeding:

Overfeeding your pets can cause damage to your water quality. Your pets would not nearly eat the amount of food that they do in a controlled environment. Feeding them with too much food will produce a larger amount of waste in the pond. What you should do is to vacuum the bottom out as much as you can, and also make sure that the drainage systems are clear and working properly.

Keeping the quality of the water:

Your pond needs filter. There are two kinds of filtration system. The mechanical filter relieves the pond of insects, wastes and dead algae (which is very important to sustain your pond's size and the number and size of your fish). The biological filtration system provides the nitrogen cycle, the one that will remove the dissolved wastes from your pond (without this, ammonia will build up which is very harmful to your pets).

You should always keep your pond clean all the time so that your pets will always live a beautiful and a stress free life. The water in your pond is where they will eat and sleep, that's why it's very necessary to keep it as clean as possible. The water of your pond should be seen as almost completely clear. It should contain no debris, and your fish should look like as if they're floating in the air. Also, you should be able to see very well the bottom of your pond.

Keeping supplies always available:

There are many supplies that you'll need to maintain your pond properly, and many of these items are very important. It is important for you to know each item's function to understand why they're needed. There are also things that you need to have on hand all the time. As you have an outdoor pond, you should expect emergency situations to occur. It's known that nature is very unpredictable, so never get into a position where an item is needed and you have no access to get it!

Preventing those common diseases:

If you have a newly-bought fish, quarantine them first from your current population. Do this for no less than a period of 15 days. Knowing that Koi Herpes Virus is activated within temperatures at 74 degrees Fahrenheit will let you expose your pet to the right conditions for the disease to reveal itself. Those that live in these conditions for a longer period of time and don't have any of the symptoms will show that they have little chances of contracting the illness.

In quarantining, isolate your fish completely away from the current population that you have. Separate the tools, water and food that you use in taking care of the new Koi. Proper procedures in hand washing should be observed too in handling both Koi and Koi items within the same period of time. Remember that quarantining will greatly reduce the chances of exposing your fish to different kinds of diseases and viruses.
