The Nitrogen cycle is a crucial process important to help achieve and maintain balance backyard ponds

Why Dissolved Oxygen Levels in Ponds are Important   Aerator systems can benefit the ecological balance of ponds by providing a continuous oxygen source crucial for healthy fish, plants and beneficial bacteria. Having an aerator in your pond is like having a dissolved oxygen insurance policy- if your pump fails you have a backup system to provide the air your pond needs to provide a healthy  ecosystem. When diffusers are placed near the bottom of ponds they infuse subsurface air increasing...

Oxygen is one of the most important factors that influences the biological balance in ponds. The amount of dissolved oxygen (D.O.) available in ponds is quite low, around 8-12mg/l (8-12ppm) compared to the air we breathe in the atmosphere which contains about 20% oxygen (or 200,000ppm). Oxygen is dissolved into ponds in 3 main ways - by the atmosphere, pond plants and aeration supplied by the movement of water.    Plants and algae are important suppliers of oxygen during daylight hours...
