Was browsing on the net and came across these. Hydor have released their version of the nanostream pumps with 4 models -

KORALIA 1 1500 l/h 4.5 W
KORALIA 2 2300 l/h 4.5 W
KORALIA 3 3200 l/h 5.5 W
KORALIA 4 4600 l/h 11 W

Hi

I have just been looking at those aswell. Look pretty good but I think they might intrude a bit too much in a nano. The koralia 1 seems to stick in the tank about 5 inches, unless I have misread the dimensions. (someone please correct me if I have).

If you look at the first pic in leo's thread - " My new ORCA 24g" you can see what looks like one in there.

Had a look at the pics. Doesn't look to bad at all. Did some more hunting on the internet and the people from nano-reef.com seem to love them...............so I ordered the koralia 1. will let you know what its like and post some pics of it in my Orca.

Koralia 1 arrived today so I removed the maxijet 1200, hydor flow and placed the koralia just under the two outlets.

one word: FU@#%NG AWESOME!!!!

I take it you are more than happy with it lol?

From what I have read, the output, although 1500lph, is quite gentle because of the wide flow.

I was a bit concerned that it might blow all the sand everywhere, but the flow seems to be split into two main directions, so you end up with really good flow all around the tank. perfect for a nano.

How's the Koralia going now,three months on ? I'm thinking about putting one in my Orca TL450 and wanted to check out some others' experiences with them first.
