Out of curiosity, the wave2k and the tunze seem to accomplish the same things. How does the tunze make waves though?

Brian,
What size tank are you using those pumps in? I am planning to use the same timer for my 90g but wondering what pumps would be best. I was thinking of just alternating two tunze 6060 but is that too much for a 90?
I posted the question in this thread too with some other notes
.
I have 2 6100's in my 72g and I'm not looking back. I'm very glad I got the 6100's, since I was debating between that and the 6000's. It was only about $150 more for the 6100's. I keep them turned down most the time, but I like turning them to 100% and watching the detritus start flying. Keep in mind my tank is BB so I'm not sure if it's too much flow for a SB tank, but I don't think it would be. I mainly bought them for my future tank which will be about 125g.
Astrivian- you can create waves with the tunze streams by using the controller. You can have one pump burst for a sec, followed by another and so forth. With 4 pumps going, I'm sure you could get a nice wave action. If you can imagine it, you can do it with the tunze controller.
Oh i guess i mean the wavebox. I didn't know there were two devices.

Hi guys,
on a lot of my tanks I'm using MJ's paired with Hydor "Flo" rotating powerheads. At usually less than 20 bucks you can't beat the price for variable flow. The little things are fairly simple to clean and rarely clog. On my 180 I have 6 of the combos tapped off a DA ReefKeeper2, along with a squid on the return lines.
Cheers,
Logan
Welcome to TR Logan! You will dig this site, lots of great people here.
That's good to hear about the hydor flo things Logan; i have been eyeing them with curiosity for a while now. I've seen some people use them on PHs for a fuge. I guess they wont work with the MJ mod though.
Out of curiosity, would you all recommend going with a closed loop, lots of powerheads, or a mix of both?

i personally like the redundancy of a mixed return system. if the main return should fail, good water movement can still be met while i change out the pump. my 2 cents.

Just to throw something new in here, i have been listening to some talks and reading articles posted by Jake Adams on his flow studies. He makes an interesting point about turbulence: it will happen given enough time. Essentially, he is coming from a chaos POV; over a large enough scale small, inevitable differences caused at the molecular level will add exponentially to create large scale changes in water movement. This results in turbulence. It is for this reason that the jet of water coming from a powerhead only goes so far int the tank before it is dispersed.
His idea is to move the entire water column in the tank with something called a gyre. He suggested placing four MJ PH's in the four corners of the tank and pointing them in a circle. Visualize a rectangular tank looking straight down. Place a PH in the upper left corner pointing toward the front, one in the bottom left corner pointing to the right side of the tank, a PH in the bottom right point toward the back of the tank, and a PH in the upper right corner pointing to the left along the back. This will cause the water to spin like a whirlpool.
okay, so after all that, has anybody tried this? His results, posted on advanced aquarist, sound promising.

That was a great article. But I was wondering about always having the flow on the corals in the same direction. I forget if there was anything like that in that article or not. (I read it when it came out.)
I think I was listening to a talk by Borneman on oxygen from IMAC a few years ago (available on their website to download) and it mentioned that having the flow in one direction causes the coral to grow differently because one side is better oxygenated.
Anyway I think the gyre is a great way to get good flow, but I would like to have enough pumps or a way to switch the direction occasionally.
how would one go about creating bi-directional gyre motion? doubling the number of powerheads doesn't seem cost effective...
I agree. I wonder if a closed loop would be easier for this and using something like a SQWD to change the flow.
