Question about plumbing??

[tony_3a]

Ok I would prefer to do a herbie with one overflow being emergency and one being drain, now only problem is what is the Max flow a 1 inch herbie drain can handle? It's a 115 gallon tank I was going to use a panworld 1200gph pump. Would the 1 inch handle that?

Thanks guys.
Btw this will be a fish only tank.
