How thick of a pond liner do I need?

• <div><p>In addition to length and width, pond liners also come in various thickness levels. Thickness is measured in mils, a unit of measurement equal to one-thousandth of an inch, with most pond liners ranging from 15 to 60 mils in thickness. The smaller the number, the thinner (and weaker) the liner. To prevent rips and tears, it’s best to choose a pond liner that’s at least 30 mils thick.</p></div>

How deep should a koi pond be?

• <div><p>A koi pond should be at least 5 feet deep to keep the fish healthy and ensure they don’t freeze in winter. Koi fish are also known for growing large, so the more room you have, the better. A larger <a href="https://www.angi.com/articles/koi-pond-sizes.htm">koi pond size</a> will allow the fish to grow bigger than a smaller one will, and the more fish you have, the bigger the pond you’ll need.

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>

Why are frogs attracted to your yard?

• <div><p>Frogs may love your yard and want to take up residence for several reasons. Yards can offer a moist environment or access to water. Frogs also eat insects—your yard may offer a steady stream of their preferred diet, such as grasshoppers, crickets, fruit flies, and more.</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>

"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."
