We run weekly water quality tests on all of our fish, alligator and turtle tanks in the Animal Department. We monitor the waters’ pH and the levels of Ammonia and Nitrates. This is important because aquatic animals are often very sensitive to chemical changes in the water they live in and drink; more so than their terrestrial relatives.
10 tanks plus 1 “control” tank (filtered water, to make sure the tests are working properly)
The end result: 33 test tubes of some very pretty colors!
