What's the best way to completely get rid of clado from a low tech tank? I have a 15 gallon tank that currently just has a bunch of wisteria (no livestock besides the standard pond and ramshorn snails) with a small amount of clado. I would like to pretty it up, have some flame moss, and add some fish, but my experience tells me if I add moss while any clado (no matter how little) is still in the tank the moss is a goner. Seems like people have had mixed results with the standard one-two punch or spot treatments. Has anyone successfully eliminated clado from their low tech tank? No livestock means I can go a bit harder than most standard treatments, but I'd like to maintain some of the biofilter if possible.
