Testing the equipment for "breakthrough"

James

In an aquarium, both 220V and 12V are used. How can I check the overall voltage in the aquarium (even approximately)? The first thing that came to mind is to put one probe of the tester in the water and the other on the ground. It should measure the alternating voltage; if there are any leaks, it should show. I'm also interested in the reaction of aquatic organisms to the voltage, as well as the systems in general. I think this information will be useful to many. I have repeatedly come across messages about cyanobacteria outbreaks due to equipment leaks. Can anyone confirm this information?

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.
