Ive replaced a bunch of fans in several coralife units but never one of those. One problem that Coralife has is (in my experience) that they change everything so very often. We have 3 different ballast types for the 65 watt pc fixtures. However the later models have been a lot easier to work with and use pigtails for thier fans. Also coralife tends to be nice about sending replacement parts. You could try to contact them after you identify which fan you need.

Yes that's the Oceanic site but if you go to Coralife's old site it redirects you here. They likely can send you a replacement if the unit is still reasonably new.
The only replacement fans I see in my distributor's catalog are 2 1/2" ones that are found in the CF aqualights. I don't know if they use the same fans universally.
If they can't help you out, let me know, I'll see what I can find out/do for you.
We replace fans in all kinds of units, all the time. I have a couple of "salvage" units that still have working fans - if it's the same small fan I probably have one here.
The fan it'self looks to be 1.5" across. Rather small, but the Clamp-on is a very compact fixture.
I was a bit suprised to find that Coralife, Oceanic and Central Aquatics were all part of the same conglomerate. Central Aquatics is a customer where I work.
