Sorry if I missed the obvious post somewhere. But I have seen a few posts where people didn't seem to understand this.
Your fish have a very unlikely chance of being injured by electrocution in the tank. So if you accidentally damage something electrical in your tank (post I was reading was about glass heaters) do not look and see your fish are fine and assume it is safe to touch the water.
If everything else in the tank is set up correctly the only time electricity can flow to ground is if you touch the water which means in all likelihood anywhere from 120-240 (or more in the case of some lighting) is going to flow through your body).
If you make the unfortunate mistake of touching something that is grounded with your other hand while touching the electrified water there is going to be a lot of current traveling across your heart.
If you get shocked once when you touch the water the best solution to checking if you have fixed the problem would be to take a voltmeter (it doesn't have to be an expensive one) with clean probes, touch one to the water and the other to something grounded. If you know for sure which prong in an outlet is ground use that.
If you are making your own DIY equipment you should familiarize yourself with usage of a multimeter. When you are done building your project you should check multiple surfaces (water, metal surfaces, etc.) to see if you have a shock hazard.
Someone else could make a guide on how to safely check things with a multimeter but I do not want to take the risk of giving misinformation resulting in injury.
Again, odds are even if the water is electrified and you shock yourself, your fish will be fine. The danger to you increases greatly if you are working with saltwater aquariums as the conductivity of the water is much greater.
The piece of faulty equipment does not have to be in the tank you are working with. If it is connected by metal or water in any way (sumps, refrugium, filters, etc.) you can still be shocked. This means people with centralized filtration could have to find exactly which tank's equipment is faulty.
Sorry for the long post but I hope it helps at least some individuals here.
