Gyre

[Bl4ckDr4g0n]

IMHO, I would likely buy the gyre over ecotech. I have 2 MP10 ES in my 65 and all of the modes except constant speed are useless. I bought them used, but I could have gotten a new gyre for the same price and I wouldnt be dealing with what appears to be inadequate flow in my tank. I am presently looking to add a third powerhead to my tank.

Also, if you do enough research you will find its fairly common for the dry side of ecotechs to get incredibly loud over time. There are some who have had success replacing bearings but most people just end up trashing their dry sides trying to fix it. The MP40 is supposed to have less issue than the MP10 because of the metal casing instead of plastic, but it is still a complaint for the MP40s as well. In the end I would save the $$ by getting yourself a gyre and use the savings to get yourself a nice led light solution or controller.

I had a Gyre XF-130 in my 40 breeder. It provided awesome flow, but I've broken three impellers within maybe eight or nine months. The new "rugged" impellers have held up slightly better, but I was still able to break one. One of my seahorses got its tail stuck in the Gyre and died, so I moved the Gyre to my 28 Nano Cube and put a Vortech MP10wQD on the 40.

The Vortech is quieter and seems to be higher quality overall, but I don't think the single MP10 is even close to matching the flow I was getting with a single XF-130--I may eventually get a second MP10. For a 40 breeder I think one XF-130 may be enough to keep SPS, but probably not with a single MP10.

For a 75 G, I would go with a pair of MP40s, which should provide for all your flow needs and then some. The Gyre provides great flow, but the impellers break way too often for me to use in a large display tank. If you go with Gyre (XF-150 probably more appropriate than XF-130 for a 75), I would recommend going with one Gyre and a second powerhead (like an MP40) on the other side to act as a backup for when (not if) the Gyre fails.

This is the complaint i've read by a few people while MP pumps are not perfect they seem to be made better.

I've had my 130 for months...probably 7-8 mths. I run it forward and back, switching every two minutes, never any issues. Haven't even done a vinegar soak yet...should do that soon though, keep putting it off

 

[JohnnyHildo]

I was looking at the bigger one. I was thinking with wide flow and enough power it would cover all the spots in the tank.

power is not an issue with these.
i have mine set at 40% forward and 60% reverse to get the results i needed. in forward any more than that results in flow so strong that it tosses my fish around and moves substrate.

 

[SFish]

Here are my thoughts so far

Gyre

Pluses

Wide flow
Cost
High flow rate
Simple to alternate two gyres with no controler

Negatives

Long tube almost 12"
Can't communicate with more then one Gyre by them self

Vortech

Pluses

1/2 the pump is outside the tank
Small foot print
Can communicate with more then one pump wirelessly
Can choose from a lot of flow patterns

Negatives

Cost
Have to by that WIFI box thing for $100
Can't angle power head

That's why I was wondering if one gyre is enough. Flow wise it is more then enough I just don't know if it will cover everything and I will have no dead spots.

 

[SFish]

I really would rather not mix and match. If I have to buy two I would get two gyres or two MPs. Wish I could try the gyres in the tank. Wondering what two of those long tubes would look like in the tank. I'm afraid it will be ugly.

Huh. I wonder if you could use just one pump that way. Mount it on the side of the tank up by the waterline. You would have enough flow to reach the other side of the tank and down the far side, then switch to a downward flow and get the side of the tank the Gyre is on as well, switching back and forth? Would that work?

 

[1jwampler]

I have a single 150 on my 150, I keep it about an inch below the waterline it moves sand off the bottom about 28" below the gyre at 1/2 power. I have had it running for about 9 mos no breakage, cleaning, just works well. I use it in a cross flow with two wavs (used to be mp40s will be switching back to mp40s) this pattern keeps the bottom spotless. I recommend either gyre or mp40s both great pumps. If you can swing both and push the 90 degrees into each other the results are fantastic.

130, running about a month---I have a 105 bow wedge, Gyre mounted at 3" down from surface running at 60% and little fish have work to do to hold position in the current. It's too much for lps in the direct flow, but sps seems to like it. It does as advertised, sends a steady flow out 3" under the surface, it hits the other wall, and rolls down and under the rockwork, to be sucked upward into the Gyre. I do not use the pulsed option, for one thing because I don't believe any motor can stand being jerked about one way and then the other; and for another, because tank joints may not stand being hammered day and night, and might weaken, even for thick glass: the manufacturer warns of that. The rolling wave is far from static, and the fish are happy.

I like the unit because it's small, unobtrusive, and neat; the cost of several powerheads, but it does the job of several, and covers the whole tank.

I would NOT recommend it until you've rid your tank of hair algae---maintenance headache, and bad for the pump.

So are you getting a rolling wave from the constant flow mode?

 

[JoeBatt]

The gyre is fantastic...I have 2x130 one at each endow a RedSea Reefer 350 and tied into 2x Icecap controllers. I have one end ramping up to around 55% and the other ramping down. Middle of the day they run together to make turbulent flow and swap it out a bit and in the evening I have a slightly lower flow. Over a year running them and not a single impeller lost.

 

[SFish]

So I found this. Thought it was a cool comparison. That kinda sells me on gyre pump. Not as bad as I thought it would be. I'm going to go with two 150s and alternate the run and shut off of them like BRS shows. The cost savings and not buying that $100 WIFI box will be an added bonus.

Thanks guys for your input and advice.

Would that work?

That's what I do but its only a 45G. Note, in reverse the Gyre doesn't fire straight down but more at a 45 degree angle. also the reverse mode is much less powerful.

 

[MorganAtlanta]

Two 150s is way overkill for a 75G. These things will move an insane amount of water. I'd go 130s, and even then you'll have them dialed down unless you are bare bottom.

 

[JoeBatt]

I agree 130 is more the size your after. 150s will be too powerful for a 75G tank. Mine is 350litres (91g) and I have the 130 and its turned down way below max output

 

[SFish]

If I run a 130 I would have to have it almost all the way up. I'm looking to run 2000gph and I may decide to go higher. The reason I'm going to run two is to change flow so one will shut off while the other runs. If I go with the 150s I can turn them down. Also the length is closer to the width of the tank so I'll get better coverage.

 

[Sk8r]

I get a rolling wave from one gyre: bear in mind I have a 105 gallon wedge tank, but also that I'm way below max power. My little fish get into the far corner bottom and swim the way little fish do when fighting current. I've had the idle thought that maybe a gyre could get action out of some fish that tend to hang still in midwater. I'm sure it's healthier for the fish to swim strongly, and it also tends to break up, say, mysis or hikari pods and send it rolling through the tank, so that one fish can't hog it all: I keep damsels, and even the little guys get their share.

 

[SFish]

Thanks sk8r

I figured I would have to turn the gyre way down but I would rather do that then run the small gyre at max speed or higher.

 

[JoeBatt]

You will be amazed at how much water the gyre pushes....see if you can check out the 130 prior. In my opinion 150 will have water over the side of your tank
