Be careful.....you don't want to be writing checks that you can't cash.

What I mean by 'gentle' flow pattern is, judging by the video for example at 2:15, the polyps are waving in gentle motion and floating objects are not moving in horrible speed like I have seen in some SPS tanks. Guess this enable animals to capture food more efficiently.
Regarding gyre, what is the reason to set such long cycle? I mean, the advantage against alternating the flow direction for shorter period of time.
It takes awhile....15 minutes at least.....to get the entire volume of water to get flowing in the same direction. The advantage of a gyre flow is that it takes much less pump power to really get a strong flow.......in other words, you get more flow with less pump power than if a chaotic, turbulent flow were used. Where I dive, the flow is usually very laminar during tidal exchanges only......so I'm actually switching direction a few times more than natural. I don't see a turbulent or alternating flow really ever where I'm diving.
As for the video, you have to realize....that before I shoot.....a bunch of things have to happen. I feed right before to make sure polyps are out...... I clean the glass..... I turn off or on flow depending what I'm shooting.....basically, I just don't walk up and shoot during normal operation.When all the pumps are on, it's a Jacuzzi in there.....making it tough to shoot. There's some staging involved.

Thank you Steve for taking your time to answer questions. Love the saying of toilet bowl and Jacuzzi, great explanation!
Also want to thank you for having oregonreef.com out there, when I feel frustrated and question if it is still worthy to pursuit, I went to visit the site for inspiration

So many questions... but I'll stick with
How do you get the hour long rotations between the Tunze pumps? I don't think their control can do that long of a period, unless you're running them through a specialized controller (Aquacontroller has a mechanism to control the pumps). I have a rather large tank that's in the planning stages and I'm wondering if I can work in one of these dry box concepts.. also whether I'd get similar effects from vortech pumps (although the box would have to be engineered a bit differently)

You can always stare at a Reef Nutrition label as the reef scene on the front is Steve's tank (he took the photo).

I use an Aquasurf module with my Neptune controller.....which allows you to input the times to come on/off. It's tedious to program all the times...but once done....it's fantastic.
For a Tunze, it's a wet box. It would be a dry box for a Vortech. Funny that you mention it, I'm also planning my next large tropical reef.... and it will be built around Vortechs in dry boxes. I've come up with a way to create a strong gyre with them.....and even have them in the middle of the tank. When I'll start...who knows....but, I'm thinking about it. I do know that when I do it again, it will have invisible plumbing.

Sniff.....sniff.....is that product placement I smell in this thread ???
It is great stuff though. My cold tank would not be the same without it.

As does being an ancient member with two BOD stints
(And we still had to pay dues to be on the BOD back then)

uh huh, but more so, look at the GHL Dosing pump
I mean just look at the specs on that puppy:
Seriously though, nicest one on the aquarium market.
