[FONT='Verdana','sans-serif']Here is a small video (1 min) of my DIY overflow @ 750 gph completely silent, also you can see I have good circulation with some nice undertow. The only problem is nothing settles to the bottom so its all floating in the tank until it gets sucked up. I wanted to thank Chompers for the idea of both surface skimming and under water suction, both overflows have a T with a 45 degree on them to provide surface and below water intake. Noise you hear is my junky digital camera not dealing with silence very well.[/font]
