RobustAire without a cabinet
The RA1-NC, RA2-NC and RA3-NC are the RobustAire 1 to 3 diffuser systems without a cabinet, for a compressor that will sit in a shed or an existing enclosure. Each system includes a 100 ft roll of weighted tubing for every diffuser.
Standard diffused aeration works in water 6 ft deep or more and is most efficient at 8 ft or deeper. We size each system and lay out the diffusers for your pond.
Circulating oxygen rich water to every layer
Fine bubbles rise from diffusers on the bottom and set up an upward flow that circulates the water, carrying oxygen rich surface water down into deeper, oxygen depleted layers. Oxygen at depth reduces nutrient release from sediments and helps hold back harmful algae blooms. Oxygen rich conditions also help the natural bacteria in your pond break down organic sediment faster.
A healthier pond bottom in summer, safer fish in winter
In summer, carrying oxygen rich water to the bottom reduces the risk of anoxic conditions there and helps reduce muck.
In winter, the rising bubbles keep a patch of ice open above the diffusers so harmful gases can escape, which lowers the risk of winter fish kills.
