Koi Pond Algae
How to Get Rid of Koi Pond Algae
Getting rid of koi pond algae is definitely something that most koi pond owners have to deal with at some point in time. Although it is usually a problem that presents itself early on, algae can really be a problem at any time. The following is an overview of what you should know when it comes to trying to control it.
Koi pond algae usually develops in a new pond because it doesn't have the right balance of animal life and plant life, which can make algae grow out of control. When you are creating your new pond, it's important to have the right equipment from the very beginning. A pond pump is one of the most essential things that you need to have. You have to make sure that you have a good pump that can move at least half of the pond's volume.
In addition to moving the water, you also need to filter it. The filter should be based on the size of your koi pond. The filter should run for 24 hours per day, every day of the week in order to get the best results. If you choose biological filtration, be prepared for the fact that it can take a couple of weeks, or even months, before it starts making a big improvement on the quality of your water.
When placing your pond, ensure that it is not in a location where rainwater is able to flow into the pond from your yard. Some people fix this by making little mounds around their pond, which is especially helpful if the pond is in a low-lying area. Runoff water has a lot of organic debris in it and these nutrients help feed the algae that is in the pond, making it grow.
Your pond is always going to have some debris in it. You don't have to physically remove it as long as it is less than ¼ of n inch deep. String algae and dead leaves can be removed with a net if you need to get it out. For this, a skimmer net does the best job. You might need a pond vacuum if the debris is too small to be removed with a skimmer net, however.
Adding enzyme products and good bacteria to a pond can help keep it healthy over time. It also reduces algae and keeps your fish healthy. Increasing the aerobic bacteria activity as part of your maintenance program will lead the decrease in disproportionate nutrients, which will give you a clearer, healthier looking pond.
If you have short, velvet algae in your pond then it can actually be good for it. It can make your pond appear more natural looking. It can also help provide oxygen to the pond and to the fish during the day and the fish like to eat on it. If you have other plants or fish in your koi pond, then you shouldn't completely remove this kind of algae.
In essence, it's not really algae that is the problem, it's the nutrient level in your pond. When an imbalance occurs, algae is able to thrive. Helping restore that balance can help decrease the amount of algae that your pond has. Still, having a little bit of algae in your pond is good for the water, plants, and fish. It can also add oxygen to your koi pond, which it needs in order to function properly. When the koi pond algae becomes too much, however, removing the excess nutrients can help control the algae growth which can make your pond clearer and healthier overall.
