I'd be weary of the petpad in Cary. The one time I went there almost every tank was heavily infested with Black Brush Algae. If it is no longer then great, but I don't know how they could have gotten rid of that much BBA over the course of a few months.
Source: I stupidly bought a bunch of java moss and riccia from them. Quarantined it and tried to bleach dip it but I still had a tank full of BBA.
