If I go with the 12 x 12 heatsink, I am thinking I will need 4, each should cover a 24" x 24" area.

Are you sure you got the Cool White correct? that is an XP-E not XP-G that most sell, didnt think anyone purchased the XP-E CW.

Both of those are about 82-85% as efficient as the recent XP-E RB and XP-G CW.

Taking that into consideration you can get away with about 180 on a mainly SPS tank.

I would recommend going with 60 NW and 120 RB though because that ratio is more aesthetically pleasing. In pods of 3 to do better color rendering.
