Seio Super Flow vs. Hydor Koralia

[gogregerson]

What do you guys think? I'm looking to replace my MJmods (as much as I like to tinker, I'd like it if I didn't have to). And no, I'm not planning on spending a grand on Tunzes. If I went with the Koralia 4 I'd end up needing at least three, this would be the cheapest way but not controllable and it sounds like people are having trouble with them. If I went with Seio 2600s I'd only need 2 and could buy a controller but I'm looking at nearly $400 for that setup compared to $150 for Koralia.

[sea monkey]

never used a seio but i sure like the Hydor Koralias

How long have you had them running?

[epidemic]

Id go for 4 modded tunze 6025, should be around 1000gps each IIRC, and that would be around $200, but you would have 4 pop cans in your tank ( the size of the koralina

[gogregerson]

What kind of mod are being done on the 6025s?

I think you can trim the insides to flow like a 6045 but I don't know for sure.

David Grigor I think knows what to do.

[gogregerson]

I assume that the Tunze Nanos are not controllable?

[spsick]

I have 2 modded 6025's in my 120, those with my return are plenty of flow for an sps tank. They're easy to mod, all you need is a dremel and about 10 minutes per pump. If you intend to get them, when they come in i'll post some pics for you on how to do it. They aren't controllable though unless you get 6055, which are over 200 a piece, but you can put a stopper in the 6025 so you can use a on/off type controller.

Please show me the mods!

What does the stopper do? Does it serve the same purpose as the stopper in an MJmod?

you are correct sir!

[gogregerson]

The other concern I would have about the tunze nanos is the strength of the magnets. I've got a 4' 150gal tank with min. 1/2 glass which is said to be the max thickness. Would this mean it may not hold real well in place?

[epidemic]

the magnets on mine will hold through the palm of my hand, thats at least 1/2thick

[gogregerson]

So it sounds like modded Tunze6025s are comparable to Koralia 4s, in cost, size, flow and noncontrollable. So all that said why choose one or the other? Anyone have experience with the Seio Super Flows?

[epidemic]

if you are arguing between the koral's and the tunze, the biggest difference is size

tunze are way smaller than both.

Plus you get a recognized name that has been the leader in high flow low wattage technology for years now. It is a brand you can trust. The korillias are nice, but I would never put any other hydor device in my tank. Also the korilias are still very new, so there is no guarantee of how long the last, etc. Seio pumps are power mongers with serious heat output. For your sake and mine, please take them off the list. :)

[David Grigor]

Size and no questions asked 2 year warranty/customer service on the Tunze. No experience with the Koralia there were rumors that they were going to stop making them but I don't really follow it to know if there are any truths. Overall size regardless of price, kept me from trying them.

Here is the post, It's pretty long but the only mod you want to do is the restricted intake. Pics are provided in the thread. No need for the stopper mod, or any of the others because the difference in flow is minimal. The mod in no way effects the reversal on the pump. After the initial breakin of about 2 weeks the only time mine stay in reverse is if it gets too dirty/caked with coraline.

They aren't controlable but I have mine on one on/off cycle per day and gives me excellent linear flow in both directions through out the day. Even if they were controllable, I'd still prefer this way. Search recent posts here on exactly how I have them set.

FWIW, I have owned a Koralia for 6 months with no problems. I don't have any personal first hand exp with the Tunze nanostreams so I won't comment on them.

[REEFSTOCK]

I've been using Tunzie (regular and nano) and Seio and happy with both.

[MNGold15]

I am running 2 Koralia 4's in my frag tank, and they are alright in something other that a show tank, because they are huge IMO. I also have 2 6025's in my 90, one is modded, one is stock. Personally, I think the nanostreams are WAY better, they put out a very nice flow, and are way smaller, and really are not that bad to look at. If you have the money, go with the nanostreams IMO.

I will say ppl on that thread are trying alot of crazy stuff they later say screwed up their pumps. The mods I did are the basic, the full blast, and the wide flow, and I would recommend them all.

The basic kicks up the flow, the full blast kicks it up to the 1200 gph, and the wide flow makes it similiar to normal tunzes, as the output on these is a bit narrower without the wide flow mod.

Could you maybe post a link, or a how to on your mods? I really dont feel like searching through that whole 29 page thread :brainoverload:

[wolmutt]

I have 2 Seio 2600's on a seio controller. Have had them for at least 6 months. The only problem I have had is that the propeller sticks sometimes when they are turned off and back on. Also, they make a little bit of noise when they ramp up from 50% to 100%. I have had Tunze, too. I have never had my Tunze pump stick when turning it off and back on, also doesn't make noise. They both work. I made the decision on what I could afford at the time.

[gogregerson]

One of the reasons I liked the Seio is that for the price of one 6025 I can get as much flow as three of them combined. However three Tunze Nanos would be drawing 18w compared to 55w on the Seio2600. Seeing that a Maxijet1200 draws 20w(for comparson), 18w for 3 pumps pushing 1000gph(modded) each that's not bad.

[sea monkey]

How long have you had them running?

2 months maybe . they are so cheap they could die in a couple years and i would still feel like i got my moneys worth : )

Just curious, do you think the mod will reduce the life of the pump ?

I think id be happy with the tunze nano or the hydor , I just choose the hydor because it was available and much cheaper.

far a size goes i think it's all relative to the size of the tank . I should note I Have the 3's and i think it looks just fine in my 33L. I bet the tunze nano's would look as good or better : )


I bet in your 110H you would be happy with either option. the hydors might stick better because the attachment is a combination of suction cup and magnet.

[wolmutt]

I just got a modded mj 1200. So far I like it, and would choose it over any seio.

[spsick]

btw my nano's magnets are fine on my glass 120 (1/2 inch glass) and could probably work on thicker! I'll post some pics of the mods for you guys later.

[David Grigor]

Roger at Tunze says it won't have any effect on pump life. Your just taking the intake restriction away. Doesn't have any impact on motor rpms or anything. Everything still covered under warranty except for the cover itself that you modify which is a $5 replacement.

:biggthumpup:



I currently have 1 modded mj1200, one k3, and 2 seio 820's in my tank. So far, I like them all. The MJ is a bit loud for me, but it pushes so much water. I have the mj and the k3 on a timer switching every 15 minutes fr 12 hours and then just the k3 at night. I'm fine if they blow since they were relatively cheap. I've had them running like this for the past 6 weeks and everything seems fine. The seio's are always on and they seem reliable enough. I also have a seio 2600 (for sale), which I decided not to use since I got the mj 1200 and don't need (read - sandstorm).


With that said. When I upgrade - will be going with tunze's or a closed loop.

[oyam123]

can you mod the TUNZE 45's?

[Goldpony75]

How much for the 2600? does it have all the hanging and suction cup brackets? how old is it?
dibs by the way.:biggthumpup:

Sounds like moded tunze's are the way the winds are blowing. Anyone already do their research and decide where to get them? Anyone want to group order with me? Looking for 4.

[gogregerson]

Now I'm thinking of holding out till the Polario shows up in a couple of months. However if one were to find a good deal and could split shipping I might still want to buy two or three Tunze 6025s, depending on the budget.

Anybody else having problems with their Tunze nano's 3-D carrier thing breaking? 2 of mine have broken from the magnet which had to be superglued back on, not really a big deal. Recently though the half circle 3-D carrier thing that holds the actual nano though have broken off in my tank on 2 of my 3 nanos. Personally, I think that sucks and I am trying to figure out a way to get some new ones since crazy glue wont work on something that has that much force on it.

Just pm roger or post in the tunze forum on RC, he'll send you new ones. He said they'll have the problem fixed in a couple weeks, and have updated the design,

[jquigley78]

Thanks, I will have to do that.

[sea monkey]

You ain't kidding!

seeing how the first hydros and tunze nanos went i think id prefer to get the second or their revision of that pump anyways .

im not sure if it is a good thing or bad thing that the polario has been in development so long.

[gogregerson]

I'm just hoping that after all this time they don't scrap the project. I know what you mean, it doesn't matter how much they test it ,until it get's into peoples tanks and systems under diferent conditions there's no way to know if they got all the bugs worked out. So if the Polario hits the market, in lets say two months, it will be safe to buy in say, a year.

[David Grigor]

can you mod the TUNZE 45's?


Because they aren't as restricted as the 6025s, the same mod on the 6045 doesn't yield a dramatic increase. IMO: Best to leave them stock.

[sea monkey]

algae free just released some new parts for their MJmod. the first part is a new bracket so it can attach to the existing maxi jet mounts (hanging and suction cup) They also include an additional prop (dumas 3004) so you have the option of having as much flow as the DIY ones did.

The higher flow and not having to purchase magnet holders makes modding a MJ much more attractive again. Especially if you already own the MJ's. the finished product is also significantly smaller than a hydor.

[clownnut]

We are quite impressed with the results as well, we are using many in the store set up. :)

[steve1600cc]

I'm new and admit it,I've taken 3 of my Sure Flow MJ's out of my Tank for the fact of way to much flow...however I can see putting said Mods into a 600 versus the 1200 which is just Insane at 2000 GPH,You all know better(I assume)LOL, so why Buy the other?
What am I missing here and all the talk of Dremmels and such I just changed the Impeller Magnet thingy and put new shroud on and was done with mine..

I have the Koralia now, and have no problem with them. I have had sieos before and they were freaking huge. I didnt care for the size at all.
