This standpipe for external overflow boxes, says it's handling 300gph. I've got about 500-600 going through my overflow per hour. This stand pipe is only 1" and I don't really have room for more than the 2", this seems to be the biggest that I can fit. Does anyone use this design and push more than 300gph through it? I'm getting worried that I may have to buy a new overflow box that can fit a bigger durso.

Well, I"ll play with it a little more - but, I just tried it.....and it doesn't :)
