Tunze 6101 kit Vs. Sequence Hammerhead.

[Jflip2002]

Alright, so Im stuck between the two. I need some flow on the 190g 60x36x20 Reef (SPS/LPS, shrooms on floor planned)

A Tunze 6101 uses 36w of eletricity, times for is 144 watts and 12,000 GPH. While the hammerhead runs 350w, while only less than 6,000 GPH. It seems like a fair difference in wattage. But when I use the reef calculator, it still puts my tank cost at around $80 a month to run (using the hammerhead).

The Tunzes seem great for doubled the flow, and less than half the wattage. But boy that $1600 really really is close to impossible for me to cough up lol.

The Disadvantage with the Hammerhead is it is probably a little noisy, and does take up some major wattage. Along with more possibilities to leak, with more bulkheads.

The Disadvantage with the Tunzes is the price tag! $1600! And you also have to have powerheads in the tank, though it doesnt bother me if theyre Tunzes, youre almost showing them off

What would you guys choose?

id choose the tunze, but thats just me

Tunzes can be moved from tank to tank, and relocated within the original tank without drilling, etc, and are much easier to use and program to get exactly what you want. BUT the closed loops are much cheaper if you know ahead of time for sure what you want.

Tunze. Best choice I made in the hobby.

My last tank was Tunzes, (2) 6100's on a multicontroller in a 125. My current 140 gallon tank I went with a sequence Dart on a Oceans Motions 4 way. I will never go back if I have the choice, much cleaner look IMO. I think a Oceans Motions is a must though.

I would (and did) go with the Tunze's,.. One other expence you have to factor in is that that big CL pump will add a whole lot more heat to the tank

You are comparing apples and oranges. The comparison should be two Tunzes (all you'll need to start out with if you have frags or small colonies) vs. Hammerhead. So its like $800 for the Tunzes vs. $700 for a hammerhead + OM 4 way. Not much of a difference. A couple other factors to help you make up your mind:

- if you go with a hammerhead, you'll need to add a Tunze or two down the road
- the hammerhead will produce more heat, which will also increase costs of cooling and costs due to evaporation
- you can change around the configuration of powerheads easier

I think you can see this one coming from another board, but why not vortechs?
- about the same cost (I found 2 new with wireless wave driver for $750 shipped from RC classifieds)
- no added heat
- barely visible in your tank
- easier to clean and move around

you can't go wrong with Tunze or Vortechs, I'm just curious why you have not included the vortechs.

I'm still waiting on the technology of the vortechs to iron itself out a bit. I'm still seeing some issues with them, and I don't like that they are pretty uni-directional. But they're a pretty cool device!

Hmmm, why would you need to add a tunze to a properly designed CLS? I don't see that if its done right. For heat, I have a 'Cuda that didn't add any heat to my tank. The Vortecs no way on an acrylic tank, to much heat.
Of course you can guess my choice! CLS, I hate the look of all that stuff in the tank, the pumps, the cords. I Know the Tunze are good product, I think its just a matter of personal preference. This tank is going to have MH if I remember correctly and once you get into big volume, I really don't see the heat from a Hammerhead being an issue.
Seriously it just boils down to preference based on the points made as each choice has pros an cons. But only you can answer which will work for you based on info given cause I think both ways will provide you with a great flow set up.

No way 5000 gph (what hammerhead is probably at after head loss) is enough for a 190g tank with SPS, now matter how you set it up. Need to have at least 8000 and preferably 10,000+ gph.

They fixed most of the kinks in the second generation with WWD. The uni-directional isnt that big of a deal when you have a tank big enough to handle 3-4 IMO. Like I said though, you cant go wrong either way.

What is this based on? Ive seen bigger tanks that were packed with SPS and less low than what I have with a Barracuda. Ill have to disagree with you there. Its how the flow is designed and utilized.

[motorslave]

Like a 200 with a Dart.

[reefermike1]

also have to consider the wide gentle flow of tunze vs. the jetstreams of cls outputs. main reason i chose koralias over a cls(tunze just too expensive for me budget). i do love the look of a tank with no powerheads though.
