Thanks for any insights into this.
Hello plant...

You're correct. Oxygen is a plant waste product, so an environment high in oxygen wouldn't be good for your plants. However, I use lengths of plastic tubing attached to an air pump and I run the end of the tubing in the bottom of my tanks. The water movement from the large bubbles circulate the water, so nutrients pass through the plant roots. I believe the water movement helps plant growth.
