Aeration is the backbone of a thriving pond ecosystem. Without it, water becomes stagnant, leading to foul odors, algae growth, and oxygen depletion. Aerators, fountains, and waterfalls help circulate the water, promoting oxygen exchange and reducing sludge buildup. This process supports fish and beneficial bacteria that keep the pond balanced. Whether you have a small garden pond or a large water feature, proper aeration ensures a vibrant, clear, and odor-free environment.
