Pond Kit Quick FAQs

How deep does this pond need to be?

This kit is designed for 2-feet of depth. Most backyard ecosystem ponds are typically 18–24 inches deep. Maintaining the 2-feet of depth helps regulate temperature and improve overall ecosystem stability.

Do I need a permit to install a pond?

Permit requirements vary by municipality. Smaller residential ponds often do not require permits, but it's always best to check with your HOA or local building department before excavation.

Can I keep fish in this pond?

Yes, these kits are designed to support a balanced ecosystem and can accommodate fish such as koi or goldfish when installed properly with adequate depth and filtration.

How loud is the waterfall?

Water sound depends on waterfall height and flow rate. The included pump has been a mainstay of the water garden industry for decades and is great for medium to heavy flows and higher head heights.

What maintenance is required?

Routine maintenance includes removing debris, seasonal cleaning, and checking pump and filtration components. When properly installed, ecosystem ponds are designed to be relatively low maintenance.

Will this pond freeze in winter?

In colder climates, surface ice may form, but ponds that are 24" deep can overwinter your fish if proper steps are taken. Review the Fall/Winter Pond Prep Guide.
