i was wondering if anyone out ther knows anything about connecting 2 tanks togethr. i saw mentioned that some of you have your octo tanks conected to your reefs. what im thinking is connecting a 30gal to my 45gal and then moveing all my equipment off the 45 and onto the 30 wich will then have a return to the 45. this way it will make the 45 look less cluttered and i dont have to worry about my octo breakin stuff. i could also use the 30 to farm stuff like caulerpa, live rock and what have you. p.s. the 30 is as tall as the 45 but alot thinner.
