Please do not ask me the "why" for this question, I am not 100% sure myself. I just brainstorm.
I know that metals are usually a NO-NO for aquariums - because they can release oxides and other stuff which is harmful for the living things inside (especially fish).
However, I think that not all metals are the same. I guess that gold should be safe (even though expensive, of course; I refer to pure gold, not cheap alloys). Stainless steel comes in mind too.
Now, does anyone have experience using stainless steel in the aquarium for any purpose? Which kind of stainless steel is better suited?
I am not a specialist, and I have in mind the following categories: general purpose, food-industry grade, medical grade. Of course, I might be wrong about my assumption.
As a "practical" use, is it possible to build an aquarium made of stainless steel? Maybe keeping one side made of glass to have it transparent?
- I did not think of welding, I have in mind using silicone for aquariums;
- I have fresh water aquariums in mind.
