It’s hard to believe that our Koi pond is seven years old. The first few years were rocky with fish dying on a regular basis. During the infancy of the pond I now know that I used too many chemicals in attempts to get rid of the summer algae. It was a learning stage. I even drained the pond after the last fish died. We refilled it and allowed the pond to “settle” for about a year before I introduced any new fish. Since then, in the last 4 or 5 years, we have grown some ‘whopper-sized’ Koi. All of the fish are healthy and have gargantuan appetites.

These photos were taken the day after our first monsoon storm. We probably had winds in the neighborhood of 50-60 mph and a drenching rain thereafter. As you can see under an overcast sky the pond weathered the monsoom just fine.

The other issue we dealt with when the pond was first established was the algae growth, especially during the summer. After the chemical fiasco, we created several filter systems looking for the best fit for our pond. The pond was built with two filter pumps that run 24/7. One services the large waterfall and one the smaller waterfall. They, by themselves, proved to be inadequate to the task of removing algae.

We searched for an external system to add to the existing system. Finally, we created our own. It consists of 4 barrels. Each has its own filter media: charcoal, quilting batting, sponges, and matt filters. The water flows through all 4 barrels and then passes through a UV light before returning to the pond. This has solved our problem. We clean out the barrel filter system once a year. It’s an all day job. However, we clean the two pump filter materials every morning and evening. It takes about 5 minutes to do so with a hose.

We have found that all the vegetation around the pond grows like a weed and some plants reseed themselves—for example, the ruella and taro. In the beginning we were timid about trimming the plants. These days we are ruthless and within a month the plants take on their original shapes.

Other than cleaning the pump filters and trimming vegetation, the pond has become stable and quite hassle-free. The photos are the pond after last night’s monsoon storm. We probably had winds of 50 mph and a bucket full of rain. We had more damage, i.e., tree limbs falling, in our yard than any damage to the pond.

You will note there is a shade cover. It has become a permanent fixture and has been up for two years. It serves a dual purpose. It shades the pond in the heat of the summer but it also protects the fish from predators. We live on a street of one acre properties with no curb, gutter or sidewalks and a great deal of mature trees. Those trees have become home to a resident owl and several hawks. We have also had herons that have visited during irrigation. All of these critters love fish. By having the shade cover it has become impossible for them to fly over the pond, spot a fish and dive for it.

It has become our oasis. It’s a joy to sit on the patio, to hear the waterfall sounds and to watch the fish, especially after I have fed them in the evening. They are voracious eaters during the summer and after they finish off the fish food that I give them, they begin their evening forage for any algae on the pond rocks that make up the submerged walls of the pond.

Would we build a Koi pond again? You bet. The hours of enjoyment and calm it offers were worth every penny of the original investment.
