Return pump size help

This is a repost from the lighting threads:

Ok getting my 300 gallon AGE shortly and am looking for any help on the what size return pump I will need. Including the stock tanks I will have around 450-500 gallons total water.

Here are some CAD pics of the tank:

Top

Side

Front to back

Overflow Limitations
Tank has basically 20 inches of overflow if you factor out the 10" for the two waveboxes.

The over flow will have two 1.5" drains and one 1" return. My fish room is in my basement and not directly below the tank. Its about 16ft vertical and 16 feet horizontal to get to the display tank. There will be an estimated three 45 degree elbows in the mix.

I used the two calc's on RC and based on what i see the overflow would handle 1350-1500gph... does this sound right? Or more? Or less?

I don't plan on putting heaters in the display tank so the more the better...

Pump Choice
Using RC's head loss calc and selecting a Blueline HD 100 it says I will have a total of 25.63 feet of head pressure, or 11.07 PSI with a flow rate of 1293 GPH. Looking at the Reeflo pumps like the Hammerhead or UNO Marlin would any of these work.. what would give me what I need...

thanks again!
