Are You a Happy "Koi Keeper" ...
Or a Frustrated "Fish Fixer" ??
Let me restate the question above another way to make an important point: there are two different hobbies we can choose from, koi keeping or "fish fixing". Ignore the need for proper aquatic facilities and ignore the very important need for excellent filtration equipment, well then, you'll eventually find yourself as a frustrated fish fixer, rather than a happy koi owner.
I don’t know about you, but I think koi keeping sounds like a lot more fun as opposed to constantly tending to sick fish!
Alrighty ... In A Nutshell Here Are The Most Basic
Yet Important
Not-To-Be-Ignored Healthy Koi Needs
A koi’s needs are basically quite simple. If you provide these five things, you will have far exceeded what 95% of garden ponders ever provide to their fish. Your koi will more than likely thrive, while theirs die, or struggle with problems of one sort or another all the time.
Side note: Please realize there are a number of other extremely important practices that should be adhered to for maximum koi health and vitality. This overview is attempting to convey the most rudimentary aspects of koi keeping for the beginner.
#1 Have as deep a pond as you can to keep down sudden temperature changes, with 4 feet deep being the optimal minimum.
#2 Have bottom drains and sloped pond bottoms so the pond cleans itself -- such easy maintenence!
#3 Have a pump properly sized to the gallonage, "head" and necessary turn-over rate required to circulate the pond water through the filters and pond itself.
#4 Have some sort of prefilter to continually get the fish waste out of the water. Look for a prefilter that is very easy to maintain. Hopefully one where it only takes a pull of a valve to flush the wastes out, quickly and easily.
#5 Have a biofilter with clean media! (This is why you need a prefilter. The prefilter keeps the biofilter from getting clogged with rotting fish excrement and other pond waste.)
The purpose of the biofilter is to do ONE thing, and one thing ONLY ... to cycle the ammonia excreted by the koi.
It must have good bacteria in order to provide high quality, stable water. It’s not just show koi that deserve these conditions. All koi deserve these conditions! PERIOD!
We all have different objectives with our water garden or pond. To me, koi keeping is such a fascinating hobby. When I started over 7 years ago, I had a 75 gallon, very poorly filtrated water garden puddle. I knew nothing about the needs of koi. I just knew I wanted some.
Well, I received four as a gift. I killed two koi fish within 2 weeks, experienced ulcers in another that I did manage to save (that's another article all by itself) and I had the other one die much later because it had an infection called "dropsy" when it was purchased. (This is also another good story for another article!)
I decided enough was enough and started to educate myself. I studied the science and ecology of water and ponds. I started to learn about koi medical care. I even attempted to gain a basic understand of the engineering involved in pond plumbing.
These are topics that you ought to try and get a moderate understanding of so you, too, can have a garden pond that will support happy, healthy koi as pets for a long, long time.

Though most hobbyists will never go this far with their training, I am an AKCA Certified Koi Health Advisor.
