Danner ProLine Pro1000 Pond Waterfall Box - 8" Spillway, Low-Profile Buryable Unit with Filter Chamber

The Danner ProLine Pro1000 Pond Waterfall Box (02477) is a low-profile, buryable polypropylene unit with an extra-wide spillway and filter-ready chambers to create a clean, aerated waterfall for ponds and water gardens.

Built from high-impact polypropylene, this compact waterfall box is engineered to sit hidden at the pond edge while delivering a steady, natural-looking sheet of water. Its stepped barb fittings accept multiple tubing sizes and the internal baffle chamber is sized to hold mechanical or biological media (media sold separately) so you can combine filtration and visual appeal in one component. The unit’s 8" spillway and 950 GPH maximum flow capacity make it suitable for a wide range of backyard pond projects.

How does the Pro1000 create a natural-looking waterfall?

The extra-wide 8" spillway produces a broad, even sheet of water that mimics natural cascades and improves surface aeration. The long weir lip allows you to stack stones securely in front of the opening for a seamless rock face appearance.

• 8" spillway opening for wide, uniform flow
• Extra-long weir lip for stable stone placement
• Baffle chamber evens flow for a smooth sheet
• Low-profile design hides beneath landscaping

Can I use the box for filtration as well as a waterfall?

Yes — this model is designed to accept filter media inside its baffle chamber so the same unit can host mechanical or biological filtration. Adding media increases beneficial bacteria surface area, helping to maintain clearer water while the waterfall runs.

• Internal chamber for filter media (media not included)
• Holds roughly 1 gallon of media-packed volume
• Promotes beneficial bacteria colonization for biological filtration
• Compatible with a range of mechanical media types

What plumbing and pump options work with the ProLine box?

The Pro1000 includes stepped barb fittings that fit 3/4", 1", 1 1/4", and 1 1/2" tubing and a pre-bored 1 7/8" inlet for easy connection. It handles pumps up to approximately 950 GPH, giving you flexibility when matching pump size to desired flow and waterfall height.

• Stepped barb fittings for 3/4"–1 1/2" tubing included
• Pre-bored inlet sized at 1 7/8" for fittings
• Maximum recommended pump flow: 950 GPH (pump not included)
• Works with standard flexible tubing and pond pump setups

How easy is installation and camouflage in my pond landscape?

The ProLine Pro1000 is lightweight and shaped to be buried at the pond edge so it stays largely out of sight. Use gravel, soil, and stacked stones on the weir lip to blend the unit into natural hardscape, and route tubing discreetly under rocks or liner for a finished look.

• Compact footprint: 8.75" W x 12.37" L x 6.5" H
• Designed to be buried and concealed by stonework
• Durable high-impact polypropylene resists weathering
• Simple plumbing connections reduce installation time

Who this is for: The Danner ProLine Pro1000 Pond Waterfall Box 02477 is ideal for pond owners, water-garden hobbyists, and landscapers who want a tidy, professional-looking waterfall that also supports biological or mechanical filtration. Choose this unit if you need a small-to-medium waterfall with flexible plumbing, easy concealment, and the capacity to add media for cleaner water and better aeration.
