You can make your pond look natural and filter water better by lining it with pond rocks! You’ll never want to go back to not having them. They’re a huge help for pond maintenance and cleaning in Maryland.

It’s Not Quite…Right

“Matt, why have you been staring into the pond?” Christina asks slowly.

“Just look at it! I mean, sure, it’s a koi pond, but it looks so man-made. It’s missing something and I can’t quite put my finger on it,” Matt replies.

Christina walks over to look into the pond. “Oh. You’re right, it’s missing pond rocks,” she points out. Matt’s eyebrows rise in surprise. “Rocks? Like, around the edges?” Christina nods. “And on the bottom, too. I’ve heard they’re good for ponds, but I don’t know why. How about we look up why they’re put in ponds in the first place. Maybe we can look at underwater pond lighting while we’re at it.”

Matt pulls out his phone and searches Google to see what he can find.

After some digging, here is what he finds and shares with Christina:

Benefits Of Using Pond Rocks

Pond rocks will make your pond look more natural than the black rubber liner will. Rocks also help protect the liner from tearing and from UV ray damage. Pond rocks give a home to beneficial bacteria that clean your pond water.

Ponds should make your home look like it was built around it. Rocks have texture, color, and character. They give waterfalls a real impact. Large stones can make a stream appear as if it changed course because of it. It’s a better look than a black rubber bottom.

But, you won’t want to just toss rocks and gravel in and around the pond. It won’t turn out looking that great…

A well-trained water feature artist uses size, shape, and character to give depth, accent, and create breathtaking effects. Water features should be constructed using different size rocks. They appear more natural and the variation in sizes creates interest. Water features with too many of the same size stones just don’t cut it.

Pond rocks can lengthen the lifespan of your liner too!

The sun’s UV rays will eventually break down and shorten the liner’s life. EPDM rubber liner generally comes with a 20-year warranty from most manufacturers, but we have seen sun-exposed liners become brittle and crack in less than that time.

The layer of rock and gravel can also protect your liner from tree branches that fall into the pond. We have seen situations where fallen branches puncture liners.

Rocks can also keep your pond water cleaner and clearer.

Pond rocks are home to beneficial bacteria, Mother Nature’s little cleaners. These microorganisms help break down fish waste and other debris that can turn into sludge. Having rocks and gravel gives them more space to colonize. It also traps sediment that may otherwise cloud the water.

We have found that these benefits help people enjoy their pond more.

Possible Downsides To Putting In Rocks

If not put in correctly, rocks might not be the best idea for a pond.

Using the wrong type of rock can be bad for the water. The wrong rocks can leak sediment into your pond, clouding and contaminating the water. That’s why we choose rocks that shouldn’t have that issue.

Rocks that are too sharp can hurt your pond by tearing holes in the liner and causing leaks. It’s rare for this to happen with a pond we build.

On the other hand, if you have the correct amount of rock artfully placed, the right type of stone, and proper filter components, you’ll absolutely love your pond!
