Hey Rich,  
I had to construct everything myself. I'm feeding mine right off my overflow. So far I have to lower my output pipe. The water is filling up 1/2 inch above the chamber. Where is your water level set for optimal skimming? 
I may end up going simple and running an MJ1200 to it LOL... 
 
Looking forward to seeing yours in action! 
Steve
