I just put two Koralia nanos in my 20 gallon. They are sweet. They put out a nice wide, gentle flow. They are also super quiet and tiny. Initial quality seems good. The way it attaches to the mount is not the greatest but seems like it will work. Now let's see how long they last.
New Koralia Nanos

I have had a Koralia 4 in my 180 for about 3-4 months or so and it has worked fairly good. The main problem I have is the impeller cover get blown off every now and then. My concern is a fish or other animal getting to close to it. I love the flow and the wide angle though. 
Keep us posted on how they do. I am thinking of doing the same. In my 20g right now, I have a maxijet 1200 with a Hydorflo, along with my CPR BakPak2 skimmer w another 1200, and an AC70 HOB modded into a fuge. I bought a Koralia 1 to replace my MJ1200 and it created quiet a sandstorm, so I took it out.
Now I am leaning more toward leaving it alone.
