NO Nitrates

So, I set up a 55 gallon for a local school with zebra danios. mollies, guppies, kuhilli loaches, cherry shrimp, and neon blue gourami's, the other day the teacher told me that the shrimp were dying. I had them test the water with a master test kit and they reported to following, 0 ppm Ammonia, 0 ppm Nitrite, and 0 ppm nitrate. this shocked me as i know that they have been topping the tank off and rarely doing actual water changes so i asked them to test it again expecting to see nitrates. They retested and sent me a picture of the test and still got 0 across the board, at this point I went down to the school with a new master test kit and tested the parameters and got the same thing twice and got a ph of 8.6. is it possible that without plants something in the tank is eating nitrates? Also, there is a large piece of driftwood in the tank so i expected a lower Ph reading any ideas on what's going on with that?

If you're using the API master test kit, you really have to shake that second nitrate test bottle. Vigorously for two minutes or more. And then you have to shake the test tube hard for one minute. Otherwise, you might not get accurate test results.
