Jerrold sounds disappointed.

Here, you can compare the critters I counted in Foster's tank against the counts for my tank and Samara's tank.

If I could only find about two pounds of creatures, I could explain the missing oxygen. But all the populations in Foster's tank seem to be correct. It's hard to hide two pounds of shrimp, or crawdads, or anything in these tanks.
