| I believe it has validity, and is logical (which is why I think most accept it as truth). However, there certainly are outliers. I mean, the guy on RC that has glass and chains and whatnot in his tank, he claims the tank is 20+ years old. He has a good bit of macroalgae in his show tank, it makes me wonder if they aren't "detoxifying" it somehow. Heck, perhaps we need to be putting metal into tanks (in jest of course). I don't know, it is just a "case-study" but I find his tank quite remarkable.
It just seems to me that we are missing something, or a few things, which I suppose keeps the hobby interesting. My best guess still remains bacterial dynamics and accumulation of bound waste by-products. Either way, changing out substrate seems to be the appropriate solution.
Could mangroves prolong the life of a tank (better, than say macro)? Would be interesting to see...
Take er easy
