I don't know how 'advanced' I feel (my first time in this subforum, lol), but regarding those who use peat for this and that (filter bags, substrate layers, tetra breeding etc), what are the opinions of the softwater gurus about using the longer, spendier 'orchid potting' types, instead of the deeper, crumblier, and more ancient layers below (a pure d mess to work with in garden OR aquarium- at least in the yard I can throw some dish soap on the bale as a surfactant, lol)? It's still Canadian, still the same species of moss, still 'unenriched' by Miracle Grow fishkilling ferts- the only difference i can *see* (without prolonged experience and testing) is it is not nearly as tannic *looking* (for those seeking soft water without black water, perhaps useful?), and a heck of a lot less sloppy. What say you? (And forgive me if it's a stupid inquiry and there's a good reason no one does it, and thank you for letting me know, if that's the case ). Thanks!
