Hi, I am a 6th grader at Monument Academy. My science fair project is on the affects of sunscreen on coral. I need help setting up small tanks to perform this project. I need at minimum 3 tanks with hard coral. What type of coral is least expensive and easy to take care of and what is the smallest size tanks that would work? Any suggestions would be helpful and if anyone has any tanks to borrow or rent that would be great.
Thanks,
Nathan
