Flow Question

[Ditto]

I want to remove the 6 Power Heads I have in my tank which are all Tunze 6055.

In at 72"x18"x18" tank.

Would you do 4 Mp40, or 3 Tunze 3? Tunze 6155 figure I would ask. Gyre are out, I had them on my other display tank and just had to many issues. MP60 with MP40 open to ideas.

It is a SPS/LPS tank and even thou the 6055 are working.

I figure I would ask and see what others would do. Thanks

Pair of 6155s on that tank would pump pretty good.

If you are used to Tunze quality and longevity, then you might not be happy with mp40 which move water quite well, but don't last as long. You also cannot aim the mp40s.

@jda - I have used post I have mp60 and Mp40 on my other tank and they do move water but agree I am replacing heads every 18 months.

Would you do 6155 over the Tunze 3?

I know a lot of people around me that bought the Stream and sold them some months later.
Apparently, they are very quite pumps due rotor tech but they are not so good as told to move water and the deflector being one of the major cause.
I did get one in hand the other day and they are huge, you will need to have a good place to hide them.

@kodo28 - thank you for the update. I saw it at reefaplooza and was concerned at the size. I could hide them on the back wall one on top of each other, but then said do I just place either 4MP40 Or Mp60’s. I was thinking 3 Mp40 on one side with two that would be synced as they have almost a clear shot to the end to the tank and the other two opposite of each other.

But not sure if I. Sync if they would make it to the other side of 72”

I do run actually 2 Mp40 on my 71" on each side.
I run them with the Profilux at arround 70% on long pulse 3mm inn anti-sync during day and flow reach to the end of opposite side and creates kind of a gyre effect.
The only issue that I have is due rock work they are placed at 1/3 and they do create kind of a swirl effect on the top of the wet side.
Actually thinking to go with the gyre 350 but not sure because I didn't wanted to lose the Profilux capability to handle the pump programming.

@kodo28 - with my tank being 72" do I place 2 MP40 on each side Sync and AntiSync then? I could go two MP60 and two Mp40 my only concern with the MP60 is any coral close to the unit will need to be moved because it pushes so much water. The gyre look nice but I just have read to many complaints about needing to clean them. The stream 3 I could place on the back wall pointing one in each direction, but based on your comments the flow would not be nearly enough.

Tank is 72"x18"x18" (182x45x45) ? I think 2 Mp40 placed on each side, would be more than enough for it. Two Mp60 and two Mp40 seems to be a little overkilled for that volume, but if you really want to go with 4 pumps better go with 4x Mp40. After all is question about the rockscape that you have on it.
On my side, I have a quite minimalist scape that allows the flow to make all the way from one side to the other on the top and go back at the button creating a gyro effect.
Pumps in antisync with pulse time set to 300 sec minimum to allow the flow to create that gyro effect. If set under that number the flow created by the pump will have not enough time to create that gyro effect. Same kind of when you start to toss a big bucked of water at the begin it is kind of hard but then water start to follow the flow and it become more easy and all water follow the flow :D
Well I was thinking to get the new serie 300 of the gyre, which apparently are better build now for the easy maintenance.

@kodo28 thanks!! Would you leave your MP40 in and get a gyre also? Could do 2 Mp4o and a gyre but like you I do not want to loose controlling it with the P4.

MP40 it is :)

So you will see no issues with two pushing the water one on each side? Or go with 4 sync on the one side and anti sync on the other side?

Well I never liked to mix brands for a specific job, so wont see me buying gyres and keep them with the Mp40's. :D
I don't wanna to loose full controlling which we have actually with the Profilux and Mp40 (knowing also that GHL is on the way to release the full controlling on MyGHL ).

I could go with the 1-10v port like I have done in the past with first generation of the Gyre + Icecap in the APEX but way to much cables and controllers and it looks like the gyre serie 300 is not compatible with the icecap.
Maybe GHL needs to release a little box to plug all kind of pump like Coralvue did with the Hydros Wave Engine. ;)

On your case I would go with 2 Mp40 and see how it goes with them and if you really need more flow then buy another 2.

@kodo28 - ok, the Mp40 came in, and talk about flow. Even at low settings the undercurrent is huge. I also borrowed a friends stream 3 to see the difference and will do some testing this weekend. But agree with you two MP40 put out more flow then all the existing pumps I have in there, but the issue I have to now figure out is where can I place them as it really has a disruptive flow within the first foot of the pump my corals.

Not sure how your scape is done and where your corals are placed but yes for sure you should avoid to have any corals directly on the outflow.

@kodo28 - Yeah have to do some moving of some corals around but was very surprised on the undertow it creates also. But I will get them to work.

I was looking at the gyre 300 series, but the Mp40 are just great pumps, dead quite, easy to clean, good looking, tons of flow and we have a dedicated controller to get the Ecotech patterns on Profilux.

I run three stream 3s, a 6040, 6055 and a 6095 and a Gyre xf330 on my 90 gallon.

They all work well. The 6040 is connected to a battery backup because it will last the longest and I have it near the surface.

The Tunze pumps are all on the back wall. I use the stream 3s to create alternating 6-hour gyres. It seems to work well. The stream 3s are very low maintenance compared with the others due to the large intake area and the magnetic levitation. Very quiet/silent too. The only issue is you can’t mount them too closely together because the magnets interfere with each other and this can cause the props to judder if they’re alternating.
