How do we measure DO? As I am filling in my pond, I am ejecting the water from about 2 feet up creating some O2 in the water, but not much. I ordered some 9" diffusers from diffuser express yesterday, and plan on beginning the process of building a diffused aeration station or two. I would like to monitor the "before and after" numbers for reference.



My momma never accused me of being to smart....
