Frequently Asked

Answers before
you call.

01

What's the difference between a koi pond and an ecosystem pond?

Koi ponds are fish-first: deep, heavily filtered, minimal plants. Ecosystem ponds are plant-first: shallower zones, bog filtration, mixed fish and native plants.

02

Can I run a stream without a full pond?

Yes — stream-only builds discharge to a hidden basin (pondless), giving you the sound and motion without the open water.

03

How much does a stream cost to run?

Most residential pumps cost roughly $20–$50 a month in electricity.

04

Will it attract mosquitoes?

No — moving water prevents mosquito breeding.

05

Do streams need liners?

Yes — EPDM liner over underlayment, hidden with natural stone and gravel.
