Hey guys! I am an elementary gifted (advanced/high ability) teacher at a low income school in Central Florida. Although it's costing me a fortune, I really felt that it would be a huge benefit for my students to learn from a saltwater tank. The experiences and the educational benefits are huge! I am so excited to watch this tank grow with my students. (I have the same students year after year.) My husband and I have a large SW tank at home, so mostly my classroom tank will be compiled from "left over" parts from that tank...which will hopefully help keep the cost minimal. (Although I'm already double the original "budget" - go figure.)
