I am re-reading some of the posts you made here in my tank log. I meant to get around to commenting about this quote above. Since I have purchased 160 lbs of EC, I have read this comment and at least one other refering to EC not being that great. I trust your experience in this mater completely, BUT, what I find interesting about it is that after lurking on these forums and reading a ton in the previous 14 months prior to buying anything, I universally read GOOD things about eco-complete, and people also backed this up with money, because I have read through a ton on tank logs here, and other places, that very often use EC.
I have read alot about MTS (mineralized top soil), but if you dont want to do DIY soil at this stage in the game (my first planted tan), and you dont want to pay a huge premium for Amanos stuff, are there better options for people than EC? I am asking this for the benefit of other people reading this thread, because as you aptly point out, there is zero chance I am pulling the substrate at this point in the game.
I can't attest to the mineral content of EC other than pointing at the bag label, but I can say I like the "look" of this substrate for one, and I also like the "feel", various size, etc. It sounds like what you are saying is that there is nothing wrong with EC (in the sense that it would be BAD for plants or fish), but that it doesnt have major benefits either. I wonder why if EC is not much better than just a simple blue colored stone substrate (like my kids tank

), I wonder why so many people seem to think it is a must-have for a planted tank?
p.s. Is Amanos stuff really the cats-meow?
