Gets the Job Done


I always go for the SeaChem meds when my fish get sick. They're more concentrated, so in the long run its cheaper than the stupid API powder packs, and they use the best active ingredients. Sulfa-based medications are much more effective against bacteria infections than tetracycilne or erythromycin. Their Kanaplex takes care of whatever this med can't, and is so much more effective than that Melafix crap or any of those powder packets other companies make.
