3 Weeks
Materials
20+ Tons of Rock & Gravel

This is a story about what happens when you do everything right. When you invest in proper care, when your ecosystem thrives, and when your fish grow so healthy and happy that they literally outgrow their home.

A Relationship Built Over Time

This pond has been part of our care since May 2023, when we first performed an Exploratory Drain and Clean service. That initial step is always about more than cleaning—it's about truly getting to know a client's pond.

Since then, we've provided routine maintenance for nearly two years. And as with any ecosystem, the more you nurture it, the more it thrives.

The Best Kind of Problem

In this case, the client's Koi grew so well that they quickly outgrew their original home. Before the snow had even melted, we received a call: the pond needed to be enlarged to properly support these thriving fish. It's the kind of problem every pond owner secretly hopes for—and we were excited to help solve it.

The Decision: Go Big

After meeting with the homeowners, the decision was made to completely transform the pond. This wasn't going to be a minor adjustment—it was a full-scale expansion designed to give those thriving Koi the space they deserved, with room to grow for years to come.

The New Ecosystem

What the Expanded Pond Now Includes

  • Intake bay for improved water circulation

  • Fish cave providing shelter and security for the Koi
  • LED lighting for dramatic nighttime views
  • Multiple streams and waterfalls adding sound and movement
  • Nearly double the surface area for happy, healthy fish
Pond with Fish Cave and Waterfalls

A Safe Haven: The Fish Cave

Every Koi pond needs a place where fish can retreat—whether from predators, extreme weather, or just to rest. The fish cave we built provides exactly that: a secure shelter integrated naturally into the rock work.

It's one of those features that the fish appreciate more than the owners might realize—until they watch their Koi confidently exploring their new domain.

Wetland Filtration System

Wetland Filtration: Nature's Water Treatment

The wetland filtration system is the powerhouse behind this pond's water quality. Plants, gravel, and beneficial bacteria work together to naturally filter the water, keeping it gin-clear without relying heavily on mechanical systems.

For a pond with growing Koi, this kind of robust filtration isn't optional—it's essential for long-term health and clarity.

🎇 Completed Just in Time for the Fourth of July! 🎇

This three-week project wrapped up right before the homeowners' Independence Day celebration—giving them the perfect centerpiece for their backyard gathering.

The expanded pond now provides a healthy environment for the original Koi—along with new finned friends—to thrive for years to come.

Pond at Night with LED Lighting

After Dark: LED Lighting Magic

With LED lighting integrated throughout the pond, the evening experience is just as spectacular as the daytime views. Watch the Koi glide through illuminated waters while the waterfalls shimmer in the soft glow.

It's the kind of feature that keeps you outside long after the sun goes down.
