Pump Size

[saltyreef]

Hey guys got a 75gallon aquarium 4' long with overflows on both ends. Just wondering what size of pump you would recommend as in gallons per hour. Also i know i saw this question somewhere before but can't find it. As I have a plumbing business I have lots of wholesalers and wondered if there is any sort of pumps they would handle that would work. Do i just have to make sure that is doesn't contain any oil or is there other variables??? Thanks for the help guys!!!
