I am getting back into the hobby after a very long break. I'm am deciding between 2 tanks A Marineland 93 cube tank w/sump and refugium and the Red Sea Max E-170 (45g). My previous tank was a DIY 50 gallon, and I remember I couldn't get tangs. While researching I read that cube tanks are not good for tangs. Is this true for tangs? If true are their any benefits of a 93 gallon over the Red Sea Max E-170 (45g) beside water volume?
