The AlphaONE LH 10.0 Filter was designed with koi keepers in mind. With its impressive capacity and efficient design, this filter can handle even the largest koi collections. Whether you're a member of the "koi a week" club or just starting out with your first koi, the AlphaONE LH 10.0 Filter is the ultimate choice for keeping your pond clean and healthy.
Despite its impressive size, the AlphaONE LH 10.0 Filter is surprisingly easy to install and maintain. The multiport valve makes it simple to switch between the different filtration modes. At the same time, the large lid allows for easy access to the media inside. And with the high-quality materials used in its construction, you can be sure your filter will last for years.
Quiet, smooth, dependable flow.
The clear lid is useful, and it backwashes without a mess. I like how it doesn’t need a big pump to work well.
I’ve been using the LH 1.75 for almost a year now. I run it with a low-head pump, and it works great with minimal energy use. The ALISS feature is a bonus—keeps things stable during outages. No regrets at all.
This AlphaONE LH‑90 is solid. Flow’s smooth, energy use is low, and it keeps water clear even when the pond’s full of fish. Easy to run
