The aquarium was sick for a month, everything was covered in slime and cyanobacteria... it looked like a dying creature, and it all turned out to be because I hit something in the pump (the pump was leaking)... I don't know how to understand that this was the issue... now, thanks to experience... well, it's better to get rid of the Chinese ones (although I still have a return from Min Yang)...

So it doesn't "hit" like that, but there is a tingling sensation with scratches on the arm. I don't know if it's salt or electricity, I want to find out.

High-voltage megohmmeters have always been used for insulation testing. The device can detect not only breakdowns but also minor leaks that can develop into breakdowns over time. That is, regular testing can help localize the problem in advance.

Well, this is the insulation of a specific device. I remembered another idea I once read about: take a piece of titanium wire, one end in the aquarium and the other to the ground, thus we have minimal protection against currents for hydrobionts.
