I need to get the cooling fan on the back of my Sfiligoi ACLS electronic ballast either serviced or replaced. As you know, Sfiligoi support in the USA is almost non-existent. Does anyone have any ideas? I've already contacted Aquarium Specialty and Aquatic Elite (Canada) without a response as of yet. Are these fans of the common variety and available at, say, Radio Shack and such or are they unique to Sfiligoi and impossible to locate otherwise?
