GPH rating with overflow durso...

[SkinnyPete]

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" coupling...so, 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.
