I have the feeling that this is not so much "re-thinking standard practice" and more "re-marketing the lazy approach to fish keeping". It's common in the hobby; a fishkeeper doesn't want to bother doing all that work, and manufactures a justification for not doing it. It's the Father Fish School Of Aquariological Philosophy.
You don't know what species of fish you have...you seem to think that they are sensitive, delicate and difficult-to-keep rather than being among the easiest beginners' fish...you keep saying more and more, revealing that you know less and less about the topic...and now, you are using the fact that an Axolotl has survived for 5 weeks (!) as evidence that you are an expert.
I have had an Axolotl who has just passed his 15th anniversary with me...that's years, not weeks. He has lived in five tanks spread over three houses in two different watersheds and is so bulletproof that I suspect he might live 5 weeks in between the couch cushions, across the room from his tank. And you are buying Axolotl-specific dechlorinators and bacterial inoculations?!?
I have the suspended lighting above most of my tanks hung in a position and at an angle that it doesn't shine directly only the front glass, which keeps algae growth to a minimum. I don't refer to this as a "concentrated zone for algae and bio-bloom" or an "engineered bio-sink"; it's simple common sense, an attempt at reducing workload.
You've dug yourself so far into this hole of BS that even if you post test results now, they will be difficult to believe because you'll need to save face by manufacturing data. But still, I hope you do get a test kit and check out your water. You actually seem to believe the nonsense you are spouting, so I think a good splash of cold hard reality in the face will do you a world of good.
