Chemical Test Data
Water Quality is a very important part of our research. Here are some of the results found by Science Research students since the beginning of the marking period.
You'll note that Tank 5, the Tilapia tank, consistently has the highest nitrate levels. This shows that there are large amounts of nutrients in this system. Where there are nutrients, there are microbes. Tank 5 has produced the most rich and varied attachment of all the systems we have studied.
