Lake and Pond Management
How healthy is your body of water? Pentair Aquatic Eco-Systems has the knowledge and experience to help revitalize your lake.
DISSOLVED OXYGEN: A KEY AQUATIC VITAL SIGN
Dissolved oxygen is a critical measure of water quality and health. Just like we depend on oxygen in the air we breathe, fish and aquatic plants rely on dissolved oxygen in water for their survival. Often caused by fertilizer and pollutant runoff, low DO can lead to the following issues:
• Oxygen stratification and thermal stratification
• An oxygen-demanding layer of organic muck
• High nutrient load and nutrient recycling
• Poor water quality
• High BOD – biological oxygen demand
• Foul odors due to anaerobic bacteria
The good news is there’s a way to bring unhealthy lakes and ponds back to life. Easily. Affordably. Naturally.

AERATION, THE NATURAL CHOICE.
By moving bottom water to the surface, aeration increases the amount of dissolved oxygen in the water, even at the deepest part of a lake or pond. Aeration can maintain or revitalize a lake or pond’s health without the need for costly chemicals or herbicides.
BREATHE LIFE INTO YOUR BODY OF WATER
Bottom-based aeration systems can restore your lake or pond. After installation, you can expect:
• Better overall water quality
• Improved water clarity and circulation
• Nutrient deactivation
• Activation of beneficial aerobic bacteria, encouraging bottom-muck decomposition
• Elimination of oxygen-related fish kills while encouraging growth of bigger, healthier fish
• Minimized algal blooms
• BOD reduction
• Reduction in herbicide and algaecide treatments and costs
• Prevention of toxic gas buildup and odors
HOW AERATION WORKS
Unconfined synergistic airlift diffusers lift and circulate extensive volumes of water, creating a vertical current through the rising force of air, moving low-oxygen water up from the bottom and eliminating stratification. Mounting two or more diffusers in a strategic manner creates a synergistic effect in causing the lift rate to be greater than the sum of the diffusers by themselves. This not only speeds up destratification, but it also saves energy.
As air bubbles expand and spread as they rise to the top, the water surface tension is ruptured into a boil area. Supersaturated gases at the bottom, including carbon dioxide, nitrogen gas and hydrogen sulfide, escape; and life-giving oxygen is absorbed.
From a single pond at an office park to natural lakes surrounding a 72-hole luxury golf resort, aeration can help improve and maintain the health of your aquatic systems.
• Golf courses
• Storm-water retention
• Lake remediation and restoration
• Community lakes and residential ponds
