As if putting one new tank together isn't hard enough, I'm putting together TWO! I want to build a 600mm cube and would like to learn from your mistakes. I was thinking slimlinme overflow with returns coming back in through the back pane. I want this to be an extremely neat cube with no pipes etc but also don't want tons of headaches. Has anyone got any plans for me of a system that has worked well for them? Anyone see any problems with the slimline fad?
