Surface (fountains)
Subsurface (diffused air)
- Requires excessive amounts of electricity to move hundreds or thousands of gallons of H20 into the air. (H20 weighs 8.34 Ibs. /gals)
- Have electrical cord in the water (hazard).
- Will generate a high electric bill.
- Aesthetically pleasing sights and sounds (soothing).
- An excellent emergency aerator due to its ability to raise oxygen levels in a centralized area. It only aerates the top portion of the water and does not disperse oxygen throughout the water resource.
- Is a poor choice for deep ponds or lakes.
- Is extremely efficient
- Requires very minimal maintenance
- NO electricity in the water
- Increased flexibility able to use multiple diffusers, if needed
- Aerates entire water resource so detrimental gases are allowed to escape
- Can move substantial amounts of water (i.e. approx. 100,000 gph)
- Will bind phosphorus which would otherwise be available for algae
- DECREASES internal nutrient loading
- Electrical bill estimate equals $12-15.00 extra per month for approximately 8 months (April November)
