Switch from 6105s to a Gyre?

[805reef]

I currently have 3 6105s on my peninsula style tank. 2 on one side of the overflow and one on the other.

I am thinking of getting rid of 1 or 2 and putting in a gyre. I want to either place it horizontally opposite the overflow or vertically next to the overflow.

Do you guys think one gyre would be enough, if I was to take out all 3 6105s?

Tank dimensions are 48x30x30.

Depends..if you are bare bottom it will...but I had to ramped mine down to 60% to keep the sand in place and put a powerhead back in there. But bare bottom I think it could do it alone.

I am not bare bottom. I wonder how bad it would be on the sand bed if I had it vertically

 

[BigDaddyStar]

I had to put mine vertically...I have the Marinedepot ultra grade sand too..it is super powerful. But I think no matter what a powerhead is necessary just to create turbulence because the wave it makes is pretty constant and regular. I am happy with the results though at 60% with a powerhead added.

What if I used 2 gyres. One on each side of the overflow and alternated them.

The reason why I am thinking of switching is because I am tired of having so many dead spots. The direct path in front of the 6105s is super strong but it dies down quick and I can't get good flow everywhere

I thought maybe the same thing. But 2 spend another 3 bills to Fi d out I dunno...my tank is a 125g 48x30x20...so seems overkill..but maybe 2 of the smaller ones would have been cool..like I said I big one will do it but sand is an issue...big time for me at least..maybe someone else has figured it out but I haven't . At 80% and up my sand is gone to one side of the tank.

I replaced two 6105 with one gyre hoping it would be enough but it wasn't close. Honestly I like the gyre allot but hands down prefer the tunze. I now have the gyre and an mp 40 both at 100% and the tunzes I feel still had more flow. The biggest down fall of the gyre is the noise. It is super loud compared to the tunze. My tank is 72x30x20. The gyre did clear up the overall look of my tank due to being much more sleek then the tunze but i would prefer the extra room taken up by the tunze for the silent operation.

Here's what two gyres look like running on my 300 peninsula
One on the overflow vertically running at 70% and the other on the center brace running horizontally running at 40%. Both pumps are running on alternating gyre mode.

Nice! That's a lot of movement in there. Everybody seems to like it

I know you have been running your gyre for as long as anybody and your tank is much bigger than mine.

Do you have any other pumps or just the 2 gyres?

Which direction is the gyre on the center brace pumping towards? (towards the overflow or away from)

Is the alternating gyre mode built in to the pumps? Meaning is only one turned on at a time and they talk to each other? Or do you just have a switch and each acts independently so sometimes they may both be on at the same time causing some "havoc"/turbulence?


[MENTION=5195]Ddavies564[/MENTION]
Thanks for the response. I am concerned about the noise which is why I am considering using 2 gyre's and not have them at 100%. Youre tank is 72" while mine is only 48". I think that might work to my advantage.

You have similar dimensions to me, your 20" is the height correct? Since I have 30" height I'm thinking if that would allow me to place the gyre higher and maybe/hopefully not effect the sand bed so much. I am now thinking of selling all 3 of my 6105's and then purchasing 2 gyres. I would prefer to have at least 2 pumps (wether its another gyre or a 6105) so that if one fails I at least have the other for some flow until I get a replacement.

i would not remove your pumps. I had 2 mp40s when i added my gyre and simply turned down the mp40s a touch. fish and corals love the turbulent flow. I really like the sleekness of the gyre but i couldn't imagine the noise of two of them. That would driver me nuts.

I don't think having it higher will make much of a difference with your sand bed as the water going down the side and back around is what is going to cause the sand to move. I plan to run the smaller gyre xf130 on my 4x2x2, and keep my 2 MP40's for the back wall and just turn them down quite a bit. The larger xf150 is crazy powerful from the ones I've seen in person. I agree with [MENTION=5140]Six2seven[/MENTION]... that way I don't have to run any of them near 100% which will reduce noise. I would suggest not selling your pumps, buying one Gyre... and see how it goes first.

Thanks for the input. The main reason for selling my current pumps is to use that money to buy the gyre, but I was very hesitant about that because I know how reliable the tunze's are and worried that if I was disappointed with the gyre I would either be stuck with it or have to pay more to get tunze replacements or mp40s'.

I think I like the plan the most of getting an xf130 and keeping my 6105's. I can then see how I like the gyre and how many 6105s I want to supplement it with and the rest I can keep for backup or sell later if I decide I don't need one or two of them.

my tank if 24" tall and i have my gyre up at the top horizontally on the opposite end of the overflow (peninsula tank). When I turn it up past 60% the sand directly below it moves. I actually love the gyre for this reason because that used to be my dead spot. but with the pump over 60% the sand in the center of my tank is completely blown away because of the interception of the mp40s brings all flow downward rapidly. I can assume two gyres or any other pump on the opposite end of the gyres will cause the same current to the floor. Thats just my opinion when the gyres are turned all the way up.

The only other pump pushing water in the tank is the return.
Both pumps are running on alternating gyre mode (yes it is a stock feature that comes with the pump)
Ok every pump u buy comes with a pump and extra set of paddles. It comes with an A & B on it and an extra set of A & B.

To get alternating gyre mode u need to take one of the sides off and replace it with the same type of paddle that's on the other side. So if u take a B side off u need to slap the A paddle on the other side. So now u have to A's on the pump will call one side A1 and the other A2 to explain how alternating gyre works. When the motor spins in forward it will shoot water out of A1 and nothing out of A2. Then when the motor spins in reverse, the A1 side will stop shooting water out and now A2 will shoot water out. Now point the side in different directions and u will have flow in both directions. I like alternating gyre mode cause the pump is always pushing water. Where pulse mode the pump is only pushing water when u set it too.

Heres a vid of it in action.

Nice! I didn't realize that is how the alternating mode worked. That cuts down on the flow since only one side is working each way, right? that's not a bad thing.

Any idea if they are planning apex support?

I want one!

Yes it cuts the flow in half. But one side still has enough power in one side to push water 8' easy.

Yes correct 30 deep 20 tall. I was thinking that to might not be such an issue with 30 tall. But I don't know. These things are surprising very powerful. I think you will be happy with its performance either way.
