honestly those OF's in that take, made me make the same thing with my 20L frag tank. i seen it on this thread and was still in the making of the tank, so i kinda stole the idea. these are some pics. not hijacking but showing that i learned and respected something custom they did. i do not take any credit. when explaining to my friends i do say i saw it on this thread.
the last one is of the side of the tank i only painted half of the side. when viewing from the from everything is black. but from the side you can actually watch the water from the OF drain down the stockman. i only painted where the OF is sili'd in and up. just makes another thing for people to look at when there looking at the system. i will definetly do this prob in most of my tank from now on.
