Is there any reason you couldn't/shouldn't take a tank that was used for SW and convert it over to FW?
No. Basically all the stuff will work (minus the skimmer) so I don't see why not. Except if it came with live rock, if the rock isn't dried out properly it will simply rot away in freshwater and you'll have a huge ammonia spike. If dried out properly though and put in it raises your pH like crazy high. Oh and you might have to re-cycle, I don't think saltwater can live in freshwater...I love this new bacteria emoticon! Thanks!
