The Atlantic BF3800 FilterFalls is a high quality waterfall filter that is part of Atlantic's Pro series.  

Using durable and long lasting materials, these units are an easy way to build a waterfall into your pond landscape while adding some beneficial biological filtration.  The unit features a rolled upper rim, providing clean lines and incredible strength.  It's easy to attach a liner to the filer as well with the included one-piece liner attachment flange.  Solid lip and molded inserts ensure a watertight seal between the liner and the unit.

Our recommendation with these waterfall filters is not to use the unit itself as the finished spillway for your waterfall.  For the most natural result, we recommend building a pool of some kind out of rocks, or other natural material,  which is then filled by the waterfall filter.  This way the waterfall filter can be hidden underneath some rocks in the landscaping, and a more natural spillway can be constructed out of rock which delivers the water back into the pond.

Frequently Asked Questions

What size of pump should I use with the BF3800 FilterFalls?

The BF3800 FilterFalls waterfall filter will work with a pumping flow rate between a minimum of 6000 gallons per hour and a maximum of 8000 gallons per hour.  Anything more than 8000 gph and the filter won't be able to keep up with the flow that the pump is providing.  Atlantic makes these units in a number of different sizes, check out the smaller FilterFalls sizes here.

What pump would you recommend for this waterfall filter?

Our favorite line of submersible pumps are made by Shinmaywa.  The Shinmaywa 7000 will do 6500 gph at 5' of head pressure.  If you need more power, we'd recommend the high volume Atlantic Tidal Wave A31 pump, which is another great pump.  The A31 model will do 8148 GPH at 10' of head pressure.   When buying direct drive pumps, it's always safest to buy a pump on the larger end since you can always dial it back to less flow if need be.  If less flow is desired, the flow rate can easily be decreased by installing a ball valve after the pump.  The nice thing about direct drive pumps is that as you close the ball valve, the pump in turn pumps less water, and also uses less electricity!  With magnetic driven pumps, the flow is also decreased, but the amount of electricity stays constant.   Not sure how much head pressure you have in your pumping system?  Always be sure before you buy a pump - see our page on Calculating Head Pressure to learn more.
