Flow plan for my new tank.. enough???

yep, rock in the middle, maybe in a couple of "towers" with swimming space between. I want a lean layout this time instead of the "wall of rock" i have usually had.

Then put your flow generator (vortech, tunze, closed loop w/eductor - doesn't really matter which one) in the hidden end off to one side and you'll have a Gyre. It works the same way as a whirlpool that builds up centrifugal force as it spins round and round. It works best with an up/down pulse. If you want really fancy then simply put a flow source alternating on each side for reversing Gyres.
