I have search the forum and the web and can't really come up with anything regarding how well the work. I know they wont flow quite as fast as teh vertical ones.
The reason I want to go with these are so the fish have the most room in the tank. I also think it would be easier to to run plumbing to the sump located behind the tank.
I am also stuck on if I should put an over flow box on the two holes? or just stick a 90, or 45 elbow. The only real video of this style I have seen is from glass-holes on their dart 3000GPH over flow. I will end up with close to this same amount since I will also be using two 2 inch holes.
