Not sure how much of the above is supposed to be public, but the cat is out of the bag now lol. It can switch directions at full power, however due to the angle of the fins on the rotors it is severely gimped in reverse, along with coming out at a 45° angle from the 'full' output instead of 180° which would be necessary to properly switch the gyre direction. Maxspect just released the details on that to the beta group four days ago, though what has been posted here isn't all of it, so I'll wait on that until I have confirmation that it's ok to talk about the rest.

7", 9", and 11" for the 35w, 50w, and 70w models. Current prototypes for the 50w are using the 11" housing.

Thanks!

[d2mini]

Hey, are those the specs for the prop housing or the magnets?
Because I found this image on retailers websites for the 50w.

We need to get all the specs out in the open...so the Chinese can hurry up and get the knock-off built and I can order it

😈

Seems even the smallest one would be too much for my 30" cube :-) guess I'll stick with my wp25's

Someone please take my money now. I want!

I was going to get one or two of these regardless, but that alternating gyre mode is what will make this really special. I can see corals loving this.

I'm being a bit nit picky here, but, I wish there was an 8hr option on the controller. That way it would alternate tide direction every other day instead of the same tide at the same time every day.

Example: 24 hrs / 8 hrs = 3 tidal directions/day Day1 = ABA, Day2 = BAB, Day3 = ABA, Day4 = BAB, etc...

With 2hr, 4hr, 6hr, and 12hr everyday day is exactly the same as the day before. 24/2 = 12, 24/4 = 6, 24/6 = 4, 24/12 = 2 (all even quotients). Which isn't a bad thing in the end, I just think giving corals and even fish a less predictable flow during any time of the day may produce more natural growth and behavior.

I'm going by what Maxspect has said in one of the Coralvue videos, which now I can't find, it was at the very end of it.

hopefully these pumps with be available to hookup to apex then you would be able to do your tides but I dont know how the apex would be able to reverse the motor direction...

Nope, no 0-10v control or Apex compatibility, they will have their own controller.

But the ebb and flow of the tides is pretty predictable.
The whole point behind the recent Gyre movement is to provide a more natural environment. All that crazy random direct flow from traditional powerbeads isn't natural.

Right, I was being a little knit picky.
I think this is a big upgrade for flow in the reef world.

A gyre can be created with just about any power head including a Maxijet. The differentiator is watts per gallon.

I'd agree, but it's also different due to the type of water movement (i.e. massive sheet vs conic).

[ridetheducati]

What benefit if any, does sheet movement have over conic?

The benefit is that you have a larger mass of water moving, so the velocity for the same gph is lower. For me, that means I can put corals closer to the pump, and replace four pumps running at about 60 percent on average with one.

Also, it's more similar to the ocean, so that may have a benefit which remains to be seen.

[phenom5]

Agree 100% with msderganc.

The sheet allows for high gph at a lower velocity. Which seems to be closer to natural reefs...at least based on my own empirical observation.

[jimrawr]

looks like this will compete for top dog against tunze and ecotech

[Yogre]

I wonder if one controller can control more than one pump?

I'm thinking two of these, one at each end of the tank running in an "anti-synch" fashion would be really slick.

I was thinking sync mode but alternating would be super sick.... anti sync would probably prevent the gyre from forming which is kind of the whole point of these pumps.

[Yogre]

I probably messed up what I meant by anti-synch...think of one pump running in forward sending a sheet of water across the surface of the tank. The other pump is running in reverse. Even at half power it grabs the sheet coming across the surface and boosts it, ducted down towards the bottom and ultimately back towards the forward running pump.

Lots of water mass moving.

[overexposed]

Ok so then we were thinking the same thing

[muttley101]

Anyone know where the cable comes out of.. Is it the middle, left, or right side? Thanks in advance!

Edit: for the production model.

That would work great with a bare bottom tank. Sounds like sand storm material otherwise.

Yeah I could easily see that happening. I don't want something that will blow the flesh off my LPS, either.

I'm thinking it might be necessary to dial them down a fair amount. I'm still looking forward to trying a couple out. If they don't work out, I'll put them up for sale and go back to my Tunzes. Hell, I've wasted money on sillier things in my life.
