16-Inch Filtering Waterfall Spillway for Ponds and Waterfall Streams up to 4,000 gallons. Includes Filter Media

🪷If you're tired of fighting cloudy water and struggling to hide bulky, unattractive filters, the HALF OFF PONDS 10" Filtering Waterfall is the solution you’ve been looking for. This compact, powerful, and intelligently designed unit is truly a 5 out of 5 stars product. It has fundamentally transformed both the clarity of my water and the aesthetic appeal of my DIY koi pond. 🫧Aesthetics and seamless integration: The primary goal of a water feature is beauty, and this unit delivers. The 10-inch spillway is perfectly sized to create a dramatic, yet natural-looking cascade without being overwhelming. The low-profile design is constructed from durable, UV-resistant plastic, making it incredibly easy to camouflage. I was able to completely submerge the body of the filter when the water is all the way to the max level. Then I was able to stack river rock and natural flat sandstones directly in front of and on top of the the spillway as I did more alterations and add-ons to the features and decorations that I wanted to my koi pond. It has since remained stable, and it's still in place! The result is a gorgeous, wide sheet of water that appears to emerge magically from the rocks, lending a professional, high-end look to my 150-gallon pond! ​🪷The filtration powerhouse with bioballs is where the FWW10 truly shines. It combines 3 critical elements for comprehensive pond health that I noticed right away: 📍The mechanical filtration: The included filter mat traps floating debris, leaves, and muck, ensuring the water is physically clean before it moves on. 📍The Biological Filtration: The massive surface area of the included BioBalls fosters incredible colonies of beneficial bacteria. This biological powerhouse rapidly breaks down harmful ammonia and nitrite, keeping the water chemistry perfectly balanced for my koi and aquatic plants. The clarity of my pond improved dramatically within 72 hours of installation! 📍Gives enhanced aeration: The built-in Venturi piping system is an ingenious feature. It actively draws air into the water flow before it hits the spillway, boosting dissolved oxygen levels. This is vital for fish health and the overall vitality of the pond ecosystem. ​📍Flow rate: The unit is engineered to handle flow rates up to 1,200 GPH, which is more than enough capacity for most small to medium-sized ponds (up to 1,000 gallons). I run mine with a 900 GPH pump, and the flow is spectacular. ​🫧Installation simplicity and durability: As an avid DIYer, I appreciate products that are truly designed for the user. The installation was incredibly fast. The unit comes with pre-drilled inlets and fittings for common tubing sizes (3/4" to 1-1/2" ID), making the pump connection straightforward. It’s light enough to manage easily, yet rugged enough to withstand being backfilled with soil and rocks. ​🪷The construction quality feels solid and reliable, reinforced by the generous 5-year warranty offered by Half Off Ponds. This commitment to longevity provides great peace of mind that this filter is a long-term investment. ​🫧My Final Verdict: The HALF OFF PONDS 10" Filtering Waterfall is the perfect blend of form and function. It provides professional-grade, dual-stage mechanical and biological filtration, delivers outstanding aeration, and creates a breathtaking waterfall display—all in a compact, easy-to-install package. It’s an indispensable component for any pond owner serious about water clarity and aquatic health. This is a must-buy! ⭐️⭐️⭐️⭐️⭐️

I have about a 1,200 gallon fish pond and this filter cleaned the water within hours. If your pond is very filthy before use, I would keep and eye on the filter for the first day it's on since it cleans the water so fast that the water started spilling over the top of the filter and ended up losing some water. Once the filter was cleaned and it cycled again that issue did not happen again. Overall, I highly recommend!

Great! Easy to install and product is as described. Recommend

This replaced an old waterfall pan that I had. It works just as described. It’s durable and good quality.

Filters the water great. Very easy to install. The price is good. Easy to put in place and fit it in with the surrounding area. Looks great!

I bought this to get a filter that is easier to clean than the one in the pond fountain. Install was super easy and the waterfall on the edge make cleaning the filter super easy. But the best surprise, was the amount of aeration this waterfall added to the pond. My pond was full of algae when I installed this and within 24 hours I could see clear to the bottom. Fish love to sit under the waterfall as well, make my pond much more enjoyable to watch.

Great waterfall design, easy to assemble. Needed over 20 minutes to remove three double-sided tape strips with a razor-isopropyl alcohol combination. The tape deserves six stars, please post the brand. Waterfall had straight sheet flow, and is a great aeration feature.

I installed so it overhangs the wood fram for a fish pond. It’s a simple, efficient design and works well. It needs to be supported well, since it’s a hard plastic which will crack if stressed.
