Hmm, well I'm not sure there's a definition for it, really... I would define it, personally and for my own uses, as a tank that is fed it's flow mostly by surge device. I suppose it could be considered a 'tidepool' style tank by some. And lots of flow too, like 50x turnover.
I use the term as a way to describe the planned flow of water through the tank, a (relatively) large volume of water moving in a dominant direction with some flowback but with low force. Or that's the idea anyhow
I'm not sure what the turbulence will be like inside the tank with my current ideas... the tiny fishes and shrimps and crabs might get blown away, or that's my fear. I won't know until I build it
