Don't forget, if you're plumbing a 150 and 121 together, with sumps, you'll need to add additives to compensate for over 300 gallons.) There's nothing wrong with the water from your reef tank for a fowlr tank. I currently drain about 20 gallons from my fowlr tank ( python straight into the sink) and refill with water from my 120 reef, then just add the new salt water into the reef. Lots less work than mixing 2 batches of salt all the time.

hmm, that's not a bad idea actually. Only problem I see here though is the duplication of equipment which I'm hoping to avoid. Two skimmers, heaters, carbon reactors, etc.. The only additives I add are calcium and baking soda and those are cheap. If the plumbing turns out to be too daunting I will end up taking your approach :-)
