I just got some amazon swords. The tank is low tech. The substrate is Seachem Fluorite. I also dose the various Seachem Flourish, albeit infrequently. Do I need to get root tabs? I read that the Seachem root tabs and the Seachem Flourish are pretty much the same thing, and even the Flourish are often unnecessary for low tech tank.
I don't use root tabs and my swords have grown over 18" tall. I used carib planting soil mixed with my existing and laterite. A good clay base will feed them plenty of iron, without dealing with tabs and such.
Never heard of that before. Hope they're being fed all natural food. I would expect any food with all that junk in it would result in crappy poop!
I haven't heard of aquarium use before, but I remember reading someplace that rabbit manure (not sure if that's the appropriate term for that critter, but, eh...) is about the only type that can be safely added directly to a garden. Most other animal manure/waste has to be composted/aged, and direct fresh application can burn plant roots.
