The video still cuts off just when you are about to see the koralia 3 come on. Otherwise the video works great. Decent resolution as well!

So the magnets hardly hold on your 120 huh? I'm intersted to hear more about this....
I don't think they will fall but any glass thicker i would probably worry abit.
With open front end, could you place a screen like the one used on the AGA overflow mods (if you know whatt I'm talking about) to help out here?
Maaybe but the shape is like a torpedo so forming something might be a pain.
The major feature that interests me on these pumps is the adjustability. On a scale from 1-10, how would you rate it?
10 but will be interested to see how long they hold their tension. They rotate around on a ball socket but there is no way to tighten. Probably won't be an issue but again just a thought.

oh boy another pump that will not work on my 1" thiickness acrylic tank. Maybe I could attached it on the overflow box. My overflow box is 1/2" thickness -- will the maget work on 1/2" acrylic?

Don't forget Xinumaster.... you still have the suction cup. Haha
By the way, what size tank do you have... it says that you are saving up for a 300 gallon, so your tank right now must be smaller so why such thick acrylic?

This all sounds so exciting. Anyone with info please chime in.

Rufio173, my tank is currently being built. Dimension of the tank is 96x30x30 about 375g on a 1" thick acrylic all around. It will be ready for deliver by the end of Jan http://reefcentral.com/forums/showthread.php?s=&threadid=988531 .
Mine is actually nothing compare to this local reefer who ordered a 60g tank from socalcreation using 1" thick acrylic http://reefcentral.com/forums/showthread.php?s=&threadid=988398 .

Just got my 4's in today, I am glad I went with them instead of the smaller one's because the flow is just enough to make things happen in my 150 when running 2 of them, need 2 more to tell you the truth. These are a no frill item that should make tunze and vortech a little worried, not because of koralia but things to come from other manufactures. I am happy with my 4's and will keep my tank in business for sometime until another item comes along that works better for $100, instead of hundreds and hundreds of dollars. I'm glad I have them and they work, makes being in the hobby a little better, instead of paying big bucks to get a comparable item. Just another bonus for us poor reefer's.
I just got my Koralia 4s and tried modifying one for kicks... WOW.

Koralia 4 review
Koralia 4 review
So, I just wanted to give my side of the story on these pumps.
First off, these pumps are very good at what they do, which is deliver generous amounts of very wide laminar flow. They are much wider than the Tunze nanostreams. I have a 6025 and while I think it's great, the flow it delivers is still tighter than I would like given that my tank is only 24" long by 24" wide.
So, I disagree with some other review on here. While the magnets may seem weak, if you remove the suction cup covers on the magnets, they become quite a bit stronger since there is not so much insulation between the magnets. Because of the sound dampening effects of the suction cup mount, I kept it on and removed the suction cup mount on the dry side magnet and got a stronger mount that way, although I don't think it's necessary because of the way in which the suction mount works. I definitely like the suction cup/magnet mount. It is really secure once placed, more so than even the nanostreams. I like to think of it this way, the suction cup is there constantly being lightly pulled by the magnet so in essence it should never lose seal like other suction cups (it's essentially as if you were personally pressing the suction cup against the glass/acrylic ad infinitum).
The pumps are large though, the koralia 4s are slightly larger than a 12 oz. soda can so these are definitely larger than the nanostreams which are roughly the size of a tennis ball or baseball.
They are less manueverable than the nanostreams, but they deliver a wider flow pattern. Still, the extra maneuverability and additional focused stream of the nanostreams may make them more idea for hitting particular deadspots in your tank.
They are just as quiet or even slightly (very slightly) than the nanostreams. Both will not bother you in the least, although in certain positions the nanostream chatters a bit more (when adjusted into a good position, they become very quiet).
Build quality is a little better on the Tunze nanostreams, although honestly if you threw both of them at the ground, you'd probably break both. I'm sure no one is thinking of using either of these pumps in that way.
Price is of course much better on the Koralias.
The koralias don't have a prop stop, but always end up going in the right direction and it's by the very simple process of pulling the impeller assembly out of the impeller cavity when it's going the wrong way and then reseating and turning the right direction once it is pulled back into the impeller cavity.
So, anyways. In all honesty, I like these pumps more than the nanostream I currently own. I would like them slighlty more even if they were at similar price points, but they are about half the price and so are far more attractive in my opinion. However, I don't have a 6045, which would be comparable to the koralia 4s in the amount of flow they deliver, so it isn't the fairest comparison, but I can't imagine that the 6045s would have a wider stream than the koralias. Now, the 6055 (will be awesome for smaller tanks where people would like to pulse the flow) is a completely different story as it supposedly can flow even more than the koralia 4s and is controllable, so I would keep the 6055 out of the comparison as comparing AC to DC pumps is unfair IMO.
I'm sure all of you who purchased one of these pumps will be really happy with the results.
Cheers,
John

Jimdogg,
My acrylic is 3/8" and I'd say I could easily mount the pumps securely on 1/2". You most likely could use it on 3/4" walls, because like I said, you just need a light pressure to secure the suction mount seal.
Also, without the suction cup mount on the dry side, you will get a stronger pull since you don't have the buffer space in between. You could try removing the suction mount on both sides for even greater distances, but honestly I like the suction mount (for it's seal as well as its sound dampening qualities) and think it works great and I don't think it is budging from that position unless I break the suction cup seal. The suction cup seal gets stronger over time until it hits its threshold as the magnet continues pulling on the suction cup.
Altogether, a well thought out pump. If it lasts the test of time, then it will surely be an amazing pump. I've got both of mine on a natural wave timer set on 3 min. on/off intervals so we'll see how that works out over the next couple of months.
I hope that info. helps a little.
Cheers,
John
