Tunze 6105 vs Gyre 150 for a 120g

[trmiv]

In the process of upgrading from a 60g to a 120g (48x24x24) which has 1/2" glass. My current MP10QD's will not reliably hold on to 1/2" glass, so I'm looking to switch to something else. My budget right now with all the other upgrade costs is around $250-300 for a pump, so I'm trying to get one pump instead of multiple. I keep mainly LPS and softies with a few hardy SPS at the top.

This tank is closer to my living room than my old tank, so I'd like to avoid Vortechs right now because even with QD they are a bit too loud this close to the TV, so I've settled on either a single Tunze 6105 (maybe add a 6095 at a later date), or Gyre 150. I actually owned a Gyre 130 previously in my 60g, but I sold it because I wasn't a fan of it in a short tank, but I think it will work better in the 4' tank. So I can't decide between the Tunze or the Gyre. The Gyre seems like it will be lower profile. I can't get a sense of the size of the 6105 though.

Is a single 6105 enough for this tank? I know flow will be more than enough, but I'm curious if I can create enough wide random flow from a single source like that. The Gyre is super wide, so I know it's more than enough wide flow, but I've heard about some reliability issues with the Gyre, but I know there has been some revisions lately. I know the Tunze gets great support from Roger on the Tunze forum. My worry on the Gyre is that the 150 is overkill from my tank, and concerns about reliability. Any opinions on this?

If you are only going with a single pump, I like the Gyre 150 better for broader flow. The Tunze 6105 output nozzle does not seem to be that large, and I imagine the flow would be more narrow. I think a better comparison would be to the Tunze 6095 (not as much flow), 6155, or 6255 which have broader output nozzles (not sure about the 6155).

I don't believe a single powerhead is enough for any tank..
But a gyre type may/should be

I think a single of either is more than enough flow for an LPS/softie tank. The 130 was more than enough flow for my 60g. I think even a single MP10 is enough flow for my 60g. But you're right that it's often better to have multiple sources of flow so it can be more random. If I went the Tunze route I'd probably add like a 6095 down the road once the funds come up a bit.

I have to say that I have been thrilled with my Gyre 150 on my 180. Been running strong for well over a year and the flow is really good. Tunzes are great too but you will need a couple of them and a controller.

Gyre 150 is an awesome pump. I ve got two WAvs, two MP40's going on the rear glass of the tank for for my next 150 build, but might have add a gyre on the side glass since it has such low presence over the glass, but excellent flow

I think I'm leaning towards the Gyre. Sucks that my old style Vortech battery backup won't work with the gyre. Guess I'll have to buy the new one.

Its not that a single can't provide enough "total flow".. Its just that it will leave dead spots as its a very directional flow..
With just a single powerhead there will typically always be dead spots somewhere/areas where crap will collect..

+1. No dead spots, multiple pumps can help solve that issue

I'm sure I'll add somethjng else at a later date, but this is a 60g moving to a 120 so I'm not chock full of corals right now. so really this question comes down to Tunze reliability vs Gyre 150 reliability. I know the Gyre has gotten better just not sure how much. I've heard they need to be cleaned frequently. I didn't have my 130 long enough to know.

 

[tommyboynj]

if you go with one pump id get the gyre. It will do a better job at killing deadspot on its own that the 6105 will. On my tank (48"x30"x26") I have a gyre 150 and 4 6095. Its a lot of flow! But i need as this is a peninsula tank and all the powerheads are set up on one short side.

I have two 150's I'm about to sell for $150 each. One is still under warranty

 

[trmiv]

Ended up buying a new Gyre 150. Bought it with a credit card that gives me an extra 2-year warranty.
