Sorry guys-

These pictures got reversed. The bottom picture is the black grow bin with the siphon and me holding the 3/4" to 1" flange that I got for it along with the 1 1/2" cap pipeand 2" strainer.

The middle picture is just to show the diffuser that I made with 2" pipe.

The top pictures show the 3/4' inch pipe that is about 18" long connected to my diffusers setup for the grow bed just out of the picuture. I did it like this to break up the water flow for the fish and to aerate the water.

I removed the diffuser and just used the 3/4" X 18" drain pipe without media and it still kept a constant flow. Tonight I pull all stops and go whole hog with a 1" drain setup. If that doesnt work, I am going to burn all of this stuff and take up something less frustrating like Golf
