Just a thought to everybody having the C2C, would it not be better to have like 4 holes the overflow drains into instead of the just one hole in the corner? That would be some serious surface skimming.
Just a thought, use dont use it!
Mashrie, I think the surface skimming would be the same but I might be wrong.
Awvince, width as in back to front? If so then if you have a look at my nano thread, you'll see that I went as narrow as possible to fit the 90 degree elbows in and a little leeway. If you mean width as in left to right, then I'd go for 100% the width of the tank.
