Tuning down the tunze turbelle

[Felixc]

I want to get 2 tunzes + multicontroller to run on my current 100g custom shaped tank and want to see what everyone thinks. I also would like to think of the future as I will be upgrading to something much bigger, perhaps 240g-300g. So if possible I would like to invest for future upgrade.

current tank: 100g, half-hexagon shaped, 55"(front) x 22"(back) x 30"(high)...it's an odd shape, but it's what space I have on the landing up the stairs. I have 150lb of rocks staked on the bottom 2/3 of the tank and the top is filled with SPS...it's a crowded tank to say the least. I have two seio 1500 facing each other at the opposite ends and it's been a challenge trying to get decent flow throughout the tank so I though of getting the tunze for stronger and more random flows.

My biggest dilema is which tunze to get for this current setup and still be able to use it on the future tank. The 6000 (1800g/h) would be nice for the existing setup but might not be for the bigger tank in the future. The 6100 (3100g/h) would be over kill right now, but perfect for the future. So my questions are for the controlling feature of the tunzes, how much can you tune it down and how long can yo run it this way without affecting it longivity and performance. I keep mainly SPS. Would love to hear back from user who have had to tune down their tunzes (6100) to 1800g/h and how the experience was. Thx.

You have a couple of options. If you do purchase the multicontroller, you can turn down the flow of the 6100's.

Another option is to purchase the 6000's. When you are ready to upgrade your tank, you can purchase the transformer for $67 to change the 6000 to a 6100.

Hi,

I have a pair of 6100's on a 7095 on one of my tanks alternating between 30% and 60 % output. Mixed reef with mostly SPS in the middle / upper rocks. Haven't had any issues doing this - I do use magnets however to angle the flow slightly higher than what you can do with the stock mounting kit.

So the output is down to about 950g/h to 1850g/h, right? What size is your tank? Why didn't you just go with the 6000 since you're not using it's full potential?

Hi,

The 6100's will not go down to 950 - at the lowest setting they will drop to around 1056 gph. I bought the 6100's for my in-wall tank which is not setup yet - sitting in a 125g for now. I also have a pair of 6000's in another 125g which is mostly softies - which would not be sufficient IMO if you were to go to a larger tank lets say a 240g SPS. So that is why I recommended a 6100 since you said you are mostly SPS and might go with a larger tank in the future.

I agree w/ Melbourne. The controllers are designed for versatility. One way to slow the flow is by getting a smaller propeller or cutting the existing propeller down, though each side needs to be balanced. I recommend buying the smaller propeller (I think it's for the 6080 - approx. 38mm dia. ilo 42mm). If I recall correctly they were under $10.

Thanks Mike, I made a mistake on the calculation. The more I learn of how capable the 6100s are, the more I am gearing towards them. With the controller they are quite versatile to fit in both medium and larger application. Any idea on what the physical sizes are on the 6000 vs 6100?

Hi,

They are the same size. Also consider the magnets for mounting unless you are running a trimless euro-spec tank or plan on using the rocks. The only difference between a 6000 and a 6100 is the transformer.
