So I took a jar then scooped it up from the muskiest part of the pond. After collecting the sample we placed the sample in a glass jar in the Biology lab at Mid Michigan Community College by a window and then it was sealed with oxygen holes. We would be checking on the sample once a week for lasting six weeks, just incase we

But the pH for my pond water sample did rise between 8.1-9.0 which is incredible and I have no idea why.
