Maxspect ‘Riptide’ Prototype Gyre Generator Pump

[jrp1588]

Very interesting, I was considering a couple Jebao RW-15's for the 125gal I'm putting together, but this has me second guessing it. I love that it's reversible, which allows for simulating tides, but I have some concerns about the feature.

1) It seems like it wouldn't push nearly as much water reversed looking at how the fins are arranged.

2) If I had it horizontally across the top and it reversed, would that then point it straight down at the sand bed and cause a sand storm?

any updates on this?

I don't think the answers to your questions are known yet, though many of us are curious

Figured it was still unknown since the beta testers don't have the feature, but just looking for speculation I suppose.

tagging along.

I have no interest in purchasing, but if I did, I would mount one horizontally and vertically in a bare bottom system. Reversing the flow every hour.

The horizontal pump would control clockwise and counter-clockwise flow and the vertical pump would bounce the flow off the front and side panels.

Looking really good.
Now I just have to find out the release date
for Europe.

Kind of antithetical to the whole concept of a gyre. That seems like it would just create chaos.

I agree.... If you have one, two or even more they need to keep the water flowing in ONE direction. Now you can reverse it on a schedule if you like. That how I have my gyre running. Clockwise flow for 3 hours and counterclockwise for 3 hours. Works for me and my colored sticks.

Anyway, I am interested in seeing how these Riptides work out. Not just from a flow standpoint but also from a reliability, controllability and quality standpoint.

To clarify, both pumps would not be on at the same time. Hypothetically speaking since I do not plan to purchase.

I'm so excited, I won a certificate for one in a raffle yesterday! Can't wait for them to release these suckers. They look like they were built for my 210 pennisula.

Well, since this is public now, here is the Gyre spanking a pair of MP40 in my tank

https://www.youtube.com/watch?v=GID4pFUNJts


The two MP40wES are synced in Reef Crest mode at 60% power, the Gyre is running in constant mode at 20% power (which is 9.5 watts from the wall!), and neither were run at the same time (so only the MP40s or only the Gyre).

Great video! Thanks for sharing. I'm very seriously considering putting one of these into my 90 gallon. I wonder how it would interact with a wave box, anyone try?

[jrp1588]

Man, the coral snow test really showed some crazy undertow with this pump. Reminded me of Scorpion from Mortal Kombat. "Get over here!"

[jedimasterben]

I wouldn't bother with any other flow devices in the tank, the goal with the gyre is mass water flow

thanks ben!! absolutely wild! are these available now? i must have missed the heads up

No, this is a prototype unit, I believe that they'll start shipping in 4-6 weeks was the last estimate I heard.

What size and How many would I need in a 180 gallon tank 65" x30" x24"?? With sps and LPs on the bottom

One 50w unit. In the video above, the two MP40 are synced on Reef Crest at 60%, the single Gyre is at 20%.

One unit is able to handle my full tank with sps dominated ? Zero deadspots?

That is correct. Once the water column starts moving, it becomes difficult to stop, you have a more energy with less resistance throughout your tank. Check out the Advanced Aquarist article I linked to above for more about mass water movement.

There are more videos shared among the beta testers of the same 50w unit in much larger tanks than yours or mine. These things are incredible.

will it destroy my sand bed? or will it leave them alone

Your tank is much taller than mine so yours should be ok, though if it is powder sand then it will blow a bit until it resettles. My sand is 1.2-2.0mm, but for some reason my MP40s were always blowing it around. So far so good with the Gyre.

[Fade2White12]

Ben, do you see much different flow patterns when mounting the pump vertically (if you haven't tried, could you)? I'm envisioning placing one of these vertically on a rear wall and creating flow that traverses around the tank.
