Do you have a koi pond? Discover how to keep your fish healthy all summer long.

A koi pond is a great way to add a beautiful water feature into your landscape, but it’s important to keep track of how the heat and summer weather can affect it. Not only are fish just as susceptible to the high heat as other creatures, but the high evaporation rates and potential for algae blooms can also put them at risk. Having algae bloom not only affect your fish, but it can keep your pond from looking its best. Fortunately, there are a few ways to keep your koi pond healthy and beautiful all summer long.

Keep Strong Sun Away

Keeping the intense rays of the sun away from your koi pond can go a long way to maintaining the temperature. One of the easy ways to keep your pond from getting too much sun exposure is to add in landscaping features to protect it, like nearby trees to give it shade. Not only will they help shade the pond, but the average temperature under a tree is significantly colder due to the oxygen they produce. If shade trees are out of the question, or you need a quicker answer pond dye and netting are both useful tools that work in places shade cannot. These help to keep photosynthesis down and help prevent algae blooms which suck up oxygen and turn your water green.

Aeration

Making sure you have an aerator in your koi pond will help keep your pond water full of vital oxygen which helps keep your fish and other pond life active and healthy. Aeration cools the water by circulating the colder bottom water with the surface water. While specific devices are made for this purpose, adding a water feature like a small waterfall or fountain into your design can help as well.  

Small, Frequent Water Changes

To help balance the warmer and colder water temperatures you can use a 10% water change method. By changing out the water in small increments, you can regulate the water temperature without shocking the pond too much by changing the water too suddenly. You want to make sure the water you add is within 10º of the original temperature to avoid unnecessary shock. Temperatures should only be raised by about one degree per hour to prevent hurting the ecosystem.

Condition Your Water

As you’re adding water make sure to recondition the water to remove any chlorine as you’re making changes. Chlorine can remove some of the fish’s slime coat which they use to keep them healthy and safe.

Feed Less

With the increased temperatures you will want to feed your koi less fish food, which is high in protein. Instead, they will supplement their diet with more algae which they can digest easier. This will also help keep the summertime algae blooms at bay.

Add Treatments In The Morning

When you’re adding in your water treatment items, like debris control substances and beneficial bacteria, it’s better to add them in the morning so that the heat and sun do not affect the additions and cause oxygen depletion.
