Hello! I have a 180g reef tank in my classroom for use in my Environmental Science classes (Grades 11&12). This thread will follow the building, filling, and growth of the tank. I have permission from the parents of my students to post pictures on a school Twitter account which is dedicated to the reef tank, and you are more than welcome to follow it to see updates on students work alongside any experiments or labs we do using the tank (www.twitter.com/monarchs_reef). I will not be posting students' pictures nor their work here, as I did not include this site on the permission slip.
