How often should I change koi pond water?

• <div><p>A good rule of thumb is to change 5% to 15% of your koi pon’s water every week. Partial water changes help keep your koi healthy, and replacing small amounts at a time prevents causing stress for the fish.</p></div>

Be sure to let your insurance company know if you <a href="https://www.angi.com/articles/who-to-hire-to-create-a-pond-on-my-land.htm">build a pond on your property</a>—they may have safety requirements in order to keep your premium from increasing. </p></div>

How deep should a koi pond be?

How do you care for a koi pond?

• <div><p>Though there are a lot of factors that go into caring for a koi pond, the most important maintenance you can do is frequent water checks using a koi pond test strip that checks the water for dangerous conditions.

"I recently had the pleasure of working with Erik from First State Ponds, and I can't recommend him enough. Erik traveled all the way from Delaware to Maryland to service my pond, which was having persistent issues with murky water. Before connecting with Erik, I had already been advised by another company to purchase a specific filter and pump. Thankfully, I found First State Ponds just in time. Erik took the time to explain that while the recommended filter might clear my water, it would require constant maintenance. He suggested a different filter and a stronger pump, but he was also willing to install the one I had already purchased if I preferred. After some consideration, I decided to take his advice and returned the original filter to have him install his recommended system. After struggling with murky water all summer, l admit, I was a bit skeptical. I wasn't sure that anything would truly work. But Erik's recommendation exceeded even his own predictions. Within just two days, the water was crystal clear! I didn't really think that was possible. There were a few challenges during installation and I admit this was 100% due to a few things I had set up prior to meeting Erik. But he handled them seamlessly, troubleshooting as needed. For the issues that couldn't be addressed that day, Erik provided me with helpful suggestions on how to finish the job myself. While I initially found the price a little high, after seeing the fantastic results, answering my many questions (including a few the following day), and delivering on everything he promised, I can confidently say he earned every cent. If you're looking for quality service, prompt responses, and impressive results, I highly recommend First State Ponds. Erik and his team are truly top-notch."
