Re: The lingo is tying my brain in a knot!!
If you use an overflow box, you will not have to drill your tank.
A return pump is separate from the skimmer. When choosing what size return pump to use, remember it becomes less powerful with the distance that the water has to travel. So if your overflow box is rated at 500 gph, you'll want a slightly more powerful pump since it will have to push the water several feet to return to the tank. If a pump is rated at 500 gph, that's measured when the water immediately exits the pump. It will be significantly less powerful after having to go through 5 or 8 feet of PVC to get back to the tank.

Re: The lingo is tying my brain in a knot!!
The rating of the overflow is the max that it can handle. The overflow will keep up with anything under 500 gph. But like biff said, the more distance that the pump has to pump, the less effective will be.

Re: The lingo is tying my brain in a knot!!
So will the return pump dictate the volume of water cycling providing the overflow can provide an equal amount of water? i.e. 1100 gph overflow (which I'm looking at) and 650gph return pump = a return of 650gph minus the loss of power due to the piping run *shrug* lol

Yep, the water can only go through the overflow as fast as the return pump can push it.

Re: The lingo is tying my brain in a knot!!
Cool, I'll hopefully be able to figure the rest out once my octo arrives and I put it all into action. I'll try to get a picture of my sump/refugium design so you guys can tear it to shreds, lol.
