How deep do you need to build a pond?

• <div><p>One of the most important parts of <a href="https://www.angi.com/articles/how-build-pond.htm">building a pond</a> is digging the right depth. Your pond needs to be at least one to two feet deep. The specifics of the depth will depend on factors such as the placement of the pond and whether you plan on having fish. If you have fish in your pond, it will need to be at least two feet deep.</p></div>

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. In addition to <a href="https://www.angi.com/articles/pond-maintenance-cost.htm">regular pond maintenance costs</a>, you’ll also need to winterize your koi pond if you live in a colder area.</p></div>

How often should pond water be changed?

• <div><p>Pond water should be changed approximately once a week. When you change it, change around 10% to15% of the water. It’s important to monitor the quality of your pond water as this will determine if it needs to be changed more often, or if you should be changing more or less than 15% of it when you do so.</p></div>

Does chlorine kill frogs?

• <div><p>Because frogs require fresh water for survival, they can die from repeated exposure to swimming pool chemicals. Chlorine dehydrates frogs, which can lead to their deaths. To ensure frogs don’t hang out in your pool for long periods, safely remove them once you spot them in your pool and install a frog log so they can easily hop out on their own.</p></div>

Should a koi pond be in the sun or shade?

• <div><p>Koi fish should be in the shade and can’t be directly exposed to the sun. Consider building your koi pond in a shaded spot or hanging an awning over the top to control the amount of sunlight coming in.

"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."
