I use a #4 and am really pleased with it's performance. They are very quiet and produce a nice flow pattern.

You might want to read some of the reviews on here. There are a lot of people with problems on theirs.
The #2 and #3 were recalled but some people are saying they're having the same problems with the #1 and #4
There are people who like them and people who's pumps have simply quit working.
I'll look for the links for you

I've had 2 of the #2s running for about a month now. I like them. I bought them because the Tunze Nanos were on back order. Now the Korelias are too. I'd like to add a couple more but we'll see how they hold up.
I have a #4 and other than the flow pattern I like it. Mine puts out a "V" shaped pattern that makes placement difficult. I won't be buying another one, either MJMOD or Seio puts out a better flow but at the expense of size and electricity and more money. it has some nice features but that crazy flow pattern killed it for me.
Well it seems I jinxed myself. One of the #2s had trouble starting up yesterday. It had a fair amount of calcium build up. I've been dosing a lot more 2-part lately. I cleaned it with vinegar but it still took some good shaking to get it running again. I'm looking into the Tunze Nanos or even possibly the Vortech.
Well I've really jinked myself. One of my Korelias has shorted and trips my GFCI when ever I plug it in. The other one still running fine for now but I plan on buying a couple Nanostreams. Their smaller and more powerful anyway.
The heat of the motor and impelller motor can cause CaCO3 to precipate out and build up, especially when dosing Cal and Alk heavily. I have the same problem with my return pump, a Velocity T4.
The other Korelia went out like the first. Premium aquatics says they weren't recalled and I need to deal with Hydor.
Ok, it's offical Hydor Koralias are CRAP!... IMO

I'm still waiting on my replacement #2s from Hydor and the Tunze Nano Streams I replaced them with work like a charm.
However, I ordered a Koralia #1 for my frag tank. I didn't want to spend the money on another Tunze, some people are gluttons for punishment. After a week of use it started triping my GFCI.
I thought the leaking current issue was isolated to the just #2s and #3s and had been resolved, obviously not. I guess I need to fork out the cash for another Tunze Nano.
