Algae tablets don't usually have much algae in the first place. There is Spirulina in some (which is a Cyanobacteria and hard to grow) and kelp in others (which dies when it gets dry), but most of the ingredients are fish meal and other non-algae. Check your labels. So no, I don't think you can grow anything from algae discs or tablets except fungus. But if you find kelp growing in your tanks I take it all back. Steev P.S. The idea of editting the comments down to a "digest" sounds pretty good. Clays comments could make an article by themselves. carrera206@comcast.net wrote: > > Can algae tablets (fish food) cause algae?
