Pond Boss Forums AERATION Should I aerate? Is placment important ?

Hi TG4 -
Placement is important - normally you would want to locate a diffuser in the deepest most central location. In your case it sounds as if you may need a diffuser on either side of the divider. Because your pond is currently only 6 feet deep,there isn't as much of a water column for the bubbles to rise and expand as there will be if/when your pond fills to 13'.
