What Am I Doing Wrong?

[bg7003]

Hey,
I got a 581 gallon per hour pump for my wet/dry. I just finished setting everything up and gluing pvc like crazy. The only thing i dont have is the actual tubes for the overflow box. I think this is my downfall. But here are some pics of my setup. Let me know what you think and where I'm going wrong. Im having such dificulty creating and maintaing a siphon...
Thanks,
Bg

Cause you're using really small ID pipes and are teeing them together on the drain side. Try just flopping them in the wet end of the filter instead...
