Tunze Nanostreams Or Hydor Koralia?

Cool, two 6025's ordered!

Andy, a maxi-mod has to have its power measured with electrical tools since once modded, it does not use the same wattage as it originally did. I can tell you from having a maxi-mod that the things are IMPRESSIVE. They put out TONS of flow, and even a modded 900 was too much for my 65g. Might have been OK if it was a barebottom acro-farm, but not for my LPS. Prolly clear into 1500GPH from one pump. If you want to measure the flowrate, you need to get a very large plastic bag, seal it to the output, run it for a short period of time with the bag immersed in water but first empty and see how much water it can fill in how much time. Basically a bucket/stopwatch. As superman mentioned, these tests were done by a few people and have confirmed those rediculous flowrates. Too bad mounting them is a PITA, and the kits are not that reliable (often noisy/chattery)

Interesting.

That sort of "ridiculous" flow rate they can give (2,000GPH+) can be achieved for 20W or less with a Tunze 6080. From the way people talk about them I thought they were going to give really huge amounts of flow, such as competing with the Tunze 6201, or even 6301 (5,283 and 7,925 GPH respectively).

Obviously it is nice that the MJ mods are cheap (the 6080 is about £100).

out of interest, what's the problems with Seios?

 

[SkiFletch]

True that Andy. Perhaps the flow just seems so massive cause of my experience with mosty moderately sized tanks .

@ombomb, the Seios have a couple drawbacks. Mounting them is difficult/cumbersome (suction cups stink), their motor is made by a company with a very poor reliability history (yet have been OK in the bast few years), and they are relatively in-efficient electrically. They used to be significantly cheaper than offerings from Tunze (and may still be depending on your locale), but with the advent of the Koralias which are priced the same as the Seios and fix most of the drawbacks, its kind of pointless to buy one IMO

 

[@ombomb]

so say... hypothetically... ( ) I'd just bought a couple of Seios on ebay... would you recommend selling them on and buying koralias instead?

 

[SkiFletch]

Ah, well I'd try and sell em if it were me

 

[sophos9]

I'm using Seio's and they have been reliable however I have several issues. One being the suction cups that erm... suck, frequently detaching themselves so the powerheads sprays the substrate and covers all the corals in sand.

The other is the efficiency, you see these things output in a too narrow stream despite its impeller design. They are large and lets face it, pretty ugly!

I've been speeking to the LFS today on Tunze and they fully recommend them!

Personally I would say sell them and get either Koralia or Nanostreams

The Tunze 6025's arrived today, upon opening the box I was amazed at how small these things are, quality seemed great. Ripped the Seio's out (thank god they had really started to get on my nerves) and put the first Tunze in...

Wow, superb flow and they create such a wide surging current I was instantly glad I got em. Added the second and with a bit of playing around and testing, the turbulence around the tank is amazing.

Great units, sooooo poles apart from the Seios (which will find their way into the sea horse tank at some point)

Fully recommend them!
