I will be putting together a 90g. (Hopefully soon but a little too busy with work rigth now to finish up my office/fish room.) I would like to eventually have a nice mix of SPS and LPS but not a crowded tank. I expect to have around 400gph from the over flow.
I was planning on having an alternating pair of the small tunze streams (1600gph; i think it is the 6060 model) on a wavemaker.
But rob made that post about the nano streams that may be a possibility also. They are a little smaller and come with a magnet mount. They come in 600gph or 1100 gph. I didn't particularly want a buch of powerheads cluttering up the tank which is why I liked the idea of two streams, but with a little smaller unit I guess I could consider one or two more but maybe even the 1100gph version would be adequate with only two.
I was also planning that with only two powerheads I may need to add a small pump to ensure good circulation in the lower rear of the tank depending on the rockwork.
Specs for 6025
Flow rate: 2,500 l/h (660 US gal./h)
Energy consumption: 7 W
Dimensions: diam. 70 mm (2.7 in.),
outlet: diam. 40/15 mm (1.5 / .59 in.)
Specs for 6045
Flow rate: 4,500 l/h (1,189 US gal./h)
Energy consumption: 8 W
Dimensions: diam. 70 mm (2.7 in.),
output: diam. 40/15 mm (1.5 / .59 in.)
Based on the specs I am still leaning towards towards a pair of 6060 since it has a much larger output so it will be a broader stream of flow.
Does anyone think alternating between two 1600gph is too much for a 90 gallon?
I have the coralife timer that can alternate every 15 mins. It would be nice to alternate a little bit faster but I think still it isn't a bad substitution for wave motion. I'm not too interested in investing the kind of money required for a controller just yet. I also dont want to clutter up the tank with a bunch of pumps. I was looking at the seio pumps until I saw that the tunzes were a little smaller.
Maybe I should consider two closed loops that could alternate current? What kind of pump would I need to get decent output from a closed loop? Probably looking for at least 1000gph that could be split to two outputs. And I would have two of those that alternated on the wavemaker. I don't want a sqwd because I don't want to maintain anything else and I don't think they had quite that much flow. Also is there a good way to make a easy connection for the pumps so I could take them out easily for regular cleaning?
I asked Roger from Tunze if I could run my 6060 on the Corallife and he said it needs to run for at least 1 hour before being shut off to prevent a shorter motor life. So I'm not going to risk my 6060 on a wavemaker.
I read that the 6025 and 6045 (their new nanostreams are able to be used every 15 minutes on a wavemaker, so I'll just use those on the wavemaker.
A quote from Roger: "The start up wears the drive unit, this can lead to the pump overheating. In theory a fifteen minute min should give a five year life."
Oh darn. Do you think that guy with the 300gal really has too much flow from a 6060? Then it would really be overkill in my 90gal! What size tank are you putting all those in?
I do really like the idea of the wavemaker so maybe I will have to just try a few 6025's. I think wildeone runs his seio on a wavemaker, though they say not to. I wonder how long it would last... At least it is not as expensive as the tunze.

I have a 75 gallon tank, 4 foot long. My Tunze 6060 is on the right side and I cannot place any coral in front of it for at least 2 feet, it is one strong little pump. When I rearrange my tank I'm going to put a rock about two feet in front of it where the stream will slam into the rock and produce a lot of random flow. In theory
I've heard the 6025s are a little weak for long tanks (I'm assuming your 90 is also 4 feet?). I'm going to put one 6025 in the lower right corner and aim to towards the front glass. My 6045 (twice as powerful), will be in the lower left corner blowing through some rockwork. I should have all three pumps going by end of January, I'll let you know how it works out, your tank is just taller than mine.
My personal (strong) opinion is that SEIOS are crap. I had both of mine crap out during MACNA (while I was gone of course) and heated up my tank to 84F and that is with cooling fans. I had them for less than a year and cleaned them with vinegar at least once every 6 weeks. Each one stopped once before MACNA, cleaned them and they were fine again, and then they seized up and never worked again. 2 SEIOS = 1 Tunze 6060 pricewise. 6060 is WAY better and worth every penny. The 6060 is rated at 1600gph, I had a SEIO 820 and 1100 (in theory 1920 gph), but I get MUCH more flow out of the 6060.
Again my strong opinion only and no I don't work for TUNZE
Well I already got one 6060 so I will probably try it with maybe a couple 6025s or something like you are doing on the wavemaker. And yes I have the standard 90g. I hope to be ready to get things up and going in Feb.
I like the tunzes because they have the large output diameter rather than a jet-like stream. And the 6060 is smaller, less wattage, and more output than the seio 1100. It will be interesting to see what the nanos are like. And I like that the nanos already have a magnetic holder on them!
i think the nanostreams have small focused outputs on them, not wide liek there bigger bothers
Yes, the specs I posted above show the outlet diameter of the nanos to be 1/3 that of the larger. So that would mean that the outlet area is much much smaller. (maybe about 15% of the 6060?)
As I have not played with different powerheads yet, I am curious how the flow is affected with the different types. Does anyone have a opinions as to which make for the better reef environment?
TUNZE specs on the 6025 (and probably the other nanostreams as well) don't seem correct for the outlet diameter. I got my 6025 and the outlet diamter is about 1.4" or 3.5cm. It is NOT .56" as I quoted above and is still posted on the TUNZE website.
The nanostream 6025 (660gph) doesn't come close to the 6060. I think I would need four of them to make up for the one 6060.
My maxijet 400 (106gph) of course seemed insignificant even compared to the 6025.
I am debating weather I should try the nanostream 6045 (1189gph) or just get a second 6060. I know they said not to use the 6060s on a wavemaker but I figure I could maybe go up to half hour periods and if I ended up killing them in a few years I could invest in the controlled ones at that time.
Has anyone tried the 6045 nanostream? And how does it compare to other powerheads you have used?

I now have one 6025, one 6045 and one 6060 in my 75 gallon. Definitely a lot of flow in there now. Here are my thoughts on how they compare:
The 6025 is the weakest and is only good for about 18" of flow from the front of the powerhead. It is still way better than any maxijet, Rio(ugh), powersweep, etc. It has more flow than the SEIO 620 and 820 (in terms of having a wider flow that covers more area). It feels stronger than a SEIO 620, but weaker than a 820, but covers more area than an 820. I use my 6025 to cover a corner of the tank that has the lowest flow (just below my 6060). It is good for that purpose, but not strong enough to use as the main flow in a large tank.
The 6045 is a LOT stronger than the 6025 and I can feel the flow from it about 36" away. I used it to replace a SEIO 1100 and it feels a little weaker, but again has a much wider flow. It is in my left rear corner and easily covers the left side of the tank (18" front to back) and all my corals are swaying on the left side. When I had the SEIO 1100 all the corals out of the direct flow were stationary.
The 6060, while rated only 500gph more than the 6045, just moves tunze more water Seriously, it moves serious amounts of water, and having a 90 gallon tank like yours, I would recommend at least one 6060 and either another 6060 or a 6045. You'll get a drop off in flow by getting the 6045, but you can also point it EXACTLY where you want it to aim, which is a big benefit.
Good right up. Thanks Brian. I actually dropped the paper with the warning about the holder tabs, but luckily I noticed it was in there TIGHT and took it out carefully. So the 6025 gets better after a break in period, eh? That would help. We may end up with the same setup. I am debating between another 6060 or a 6045 now. I think the 6060 is awesome but I am leaning toward the 6045 and all three should give me plenty of flow and coverage.
