so i recently just bought a 135 gallon tank was wondering how big of a return pump i would need its only traveling like 2 ft high since the sump is attached to the back of the tank

Well it all depends on the size of the sump you have. I would say either a Mag-drive 12 or 18. You want your flow to be 10-20 times the size of the tank, so that would put you at 1350-2700gph.

Most of the guys on the forum have been saying 3-5 times at most and the rest is done with circulation pumps...

think an 1100 gph pump would be adequate?? and get some pretty strong powerheads?

and the sump is built onto the tank its really long but shallow its not very big at all
