No offense Doc... But I'm kinda hoping you'll have to settle for the 220. Because even if you do use the 125 as a sump, it's true you'll be above my current gallonage of 300.
But you see, since there's no way in hell I'm upgrading to a tank size bigger than my current one simply to beat you, I could very easily upgrade to a 125 gallon sump too. Which would, again, put my overall gallonage higher than yours.
SO LET'S GO 220!!!!!!!!
