Luis, In time. Thanks. I will check both sources out.
I suppose some people - myself included in the past - used mulm from an active aquarium to 'innoculate' the substrate of a new set up. I imagine at least one advantage of using either Dupla or ADA products is that neither is contaminated with other things you might not want in a new substrate. Presumably, mulm might carry algae spores or what not...
