General Discussion - Science Teacher in need of help!!!

I know I have done this before last year and the community was so helpful. My name is Chris Saunders and I teach a class called tanked for middle school students we are in the midst of this class and I am wondering if I could have some help with supplies and livestock. I am trying to make a coral reef tank out of a red sea 170s tank I would love to put in a refugium as well as clowns and Bangia Cardinal fish with corals and anenomes. I want to show the students the mutual relationships that the fish have with the corals and anenomes and how to create a balances ecosystem one reason I would like to get a refugium going as well so then they could show what our tank is doing and compare it to the reefs around the world. We would love to be able to give back to the community as well as have you as experts come in and talk to the students about lighting, chemicals, and other important topics! If there is anyway that you could donate any item that would be amazing! The tank has been running for almost a year with sand in it the salinity now is sitting at 1.020 SG. Please if there is any way you could help that would be amazing! Here is a picture of the tank. I am located in Marriot-Slaterville in North Ogden. Please let me know if you would be willing to donate anything to our cause!
