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

[nlreefguy]

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.

If you have the source at the overflow end at the bottom,moving down the tank and the sump returns at the surface at the opposite end you will get a barrel effect that will guarantee surface water gets to the overflow and detritus is picked up and into the water column.
