Where water, nature & koi live in harmony
SevenKOI designs, builds, stocks and cares for koi ponds across South Florida. One landscape professional handles it all: the pond, the life support, the fish and the upkeep, so your water garden stays healthy for years.
Tip: tap the water and the koi will come to feed
A living garden you can feel
The sound of moving water. Koi gliding up to greet you at feeding time. A quiet place to slow down at the end of the day. That is what a well-built koi pond gives back.
SevenKOI is led by a landscape design professional with years of hands-on experience building ponds, fountains and waterfalls in South Florida. Because we understand both the landscape and the life inside the water, we can take care of everything: the design, the materials, the filtration, the fish and how many of them your pond can truly support.
- Ponds designed for the health of the fish, not just the look
- Materials, pumps and filters sourced and installed for you
- Koi chosen, allocated and acclimated by people who know them
- Ongoing care, so the water stays clear and balanced
