So, in all of this I actually agree with you quite a bit, and curious as to why you didn't say that off the hop?The point I'm trying to get at is people claiming stability is key until they run into problems.
Then it's throw anything and everything at the tank for a quick fix, which just goes against the whole point. I believe your bacterial system needs stability along with the basics.
Along with this is people keeping their tank too sterile. The oceans are far from sterile.
Our tanks are little ecosystems. We need to provide the right things for it, but not declare certain parameters must be followed or certain failure will happen.
