Aeration of lakes is the economical way to circulate, clean and clear large volumes. Most public pond and lake maintenance professionals use aeration for algae control in ponds. Aeration pumps for lakes, lake aeration compressors produce millions of fine bubbles in lake water that start from greater depths and rise farther for longer, so they lift and circulate huge quantities of water. Larger doses of bacteria, like the pond bacteria block, treat lakes for a month or more.
