How it compares
High-volume electric aeration versus surface fountains
For larger, deeper ponds, moving enough air matters more than moving water at the surface. Here is how the HD550 compares to a common surface approach.
Common approach
Surface fountains
- Move water mostly at the surface, leaving deeper water untouched
- Do little to circulate the full depth of a large or deep pond
- Often place the pump or compressor without a dedicated protective enclosure
