How it compares
Bottom-diffused aeration built for depth
Surface fountains move the top layer of water and leave deeper zones untouched. The HD250 OB Edition compressor pushes air to the bottom of the pond so the whole water column stays in motion.
Common approach
Surface fountains
- Circulate mainly the top layer of water
- Reach shallow ponds but struggle with real depth
- Sit in the open, exposed to the elements
HD250 OB Edition
Deep electric aeration
- Designed to aerate ponds and dugouts
- Rated for a surface area of 1 acre or less
- Housed inside an outbuilding or heated shed
