choice of substrate
Since my first planted tank has been nothing but issues, albeit it has been a learning experience, I've been planning out my next planted tank. My biggest dilemma lies in choosing a substrate.
I've got basically two choices, or at least I think I do.
A. Buy something like Flourite, Eco-complete, Profile, Onyx sand etc. and let that constitute my entire substrate.
B. Use my laterite at the base of the substrate with a little peat, and fill the rest in with an inert sand/gravel. Of course, I'd press in root tabs for the plants that use their roots for reaching nutrients. However, that's where my problem is. I wanted to use some hardy plants like pygmy chainsword, but I'm afraid if I press in root tabs for them then they'll take over the tank. And if I don't, they won't get the nutrients they need to really flourish.
Does anybody know if this plant does well leaching nutrients from the water column?
