Making a waterfall for a pond is fast and easy.

The Waterfall Filter creates beautiful waterfalls quickly and easily. The mesh bag allows for the addition of bio-media (6-8 liters of Bio-Activators) for effective filtration for ponds up to 1000 gallons. Easy to install and blend into landscape. Use with pumps 500 to 4500 GPH. 2-year limited warranty.

Easily Create a Beautiful Waterfall
The Waterfall Filter allows to you to easily create a beautiful waterfall for your pond. This easy-to-assemble filter provides both mechanical and biological filtration and can be easily hidden with rocks and pond decoration. Benefits of the Waterfall Filter include increased aeration for your pond and cleaner and healthier pond water.
  • Waterfall disappears into landscape
  • Use with pumps between 500 and 4500 gallons per hour
  • Use with 1 in. or 1 ¼ in. ID tubing

How it Works
  1. Pond water is pumped into the bottom of the filter.
  2. Water rises upwards through a fiber mat, which traps suspended dirt and debris.
  3. Water flows through lava rock or Bio-activators (not included) where beneficial bacteria naturally colonizes to convert harmful pollutants into relatively harmless nitrates.
  4. Water exits the filter via an extra-long spillway to create a waterfall. Ridges on the underside of the spillway prevent dripping.

Mechanical Filtration
Pond water is pumped into the bottom of the filter. It rises upwards through a fiber mat, which traps suspended dirt and debris.

Biological Filtration - Lava Rock or bio-media in Mesh Bag
Beneficial bacteria will naturally colonize on the rough surfaces of the lava rock or other bio-media (not included) and convert harmful pollutants in the pond water into relatively harmless nitrates. Nitrates are absorbed by aquatic plants and can also be removed from the pond through partial water changes. This process is known as the nitrogen cycle.

The open-profile bio-activators offer a superior filtration performance over closed bio-media and lava rock. These bio-activators have been perfected and used in the commercial aquaculture industry where demanding filtration is required due to extreme environmental conditions. The advanced technological design of the bio-activators provides a large active surface area for the beneficial bacteria to colonize.

Rated 5 out of 5 by from Awesome waterfall, awesome filter Clears and maintains a 1000 gal quickly/cleanly. Outstanding waterfall effects and sounds. Just a few precautions.....Be careful of the depth of the pump. Should a leak develope and pump is on very bottom it could drain the pond if not vigilant. I placed mine at half depth for that reason. Also give the waterfall/filter a small horizontal forward tilt toward the falling water. At first mine was installed slightly tilted back, filter clogged and started slow overflowing out the back of the filter instead of forward into the pond pond. Doesn't take long to drain the pond that way. So carefully monitor the sequence of filter cleaning so water continues to flow freely into the waterfall.With these guidelines, you will love the convenience of above ground filter cleaning with the beautiful looks and sounds of the waterfall. Enjoy!

Rated 5 out of 5 by from This waterfall filter has a strong waterfall effect and does a great job of filtration. Also has a lot of room for a abundance of lava rock Great product, but way too overpriced, it's only a pail with a large mouth. Should be a lot cheaper.

I'm having issues with lost water because the water doesn't always flow from spillway with "oomph" - it sometimes dribbles, which is then trapped back in rocks underneath filter and outside the pond. Any suggestions other than using liner?

Asked by: Mike M
If it is dribbling, either your pump is too small or it is in need of maintenance. I would address the pump issue first (you want at least 1000 gph at the waterfall, including head, etc.). If this doesn't completely take care of the issue, and you do not want to use a liner, you can place mortar in between the rocks and seal the outlets this way. BREX

My pump has a 1/2 inch tube for the exiting water. How do I get the 1/2 inch tubing to convert to a 1inch tube to go into the waterfall filter?

Asked by: bassmaster
Thanks for asking, bassmaster. You should be able to find a simple adapter at your local hardware store that will allow you to do this.

Hi just like most of the questions above I need the fitting to attach 1 1/4 tubing to the tetra pond 26596 waterfall spillway.Apparently it is not included. How and where can I get one?

Asked by: Marshmallow
Hi Marshmallow, Actually, it is indeed included in the bag of parts that comes with the kit, normally. Most requests are due to folks losing or breaking an adapter. We will reach out to you directly. BREX
