On grounding aquarium equipment

[Swimfins]

I have my 2 pronged filter, canopy light, and hundred watt heater plugged into an extension that has a third prong. Is it sufficently grounded?
I read somewhere that stray electrical current can bother electrical fish (like Black ghost knife) and am I sufficiently protected if I stick my hand in the aquarium? Or should I turn everything off when I do?

Have a nice day.

you're fine.

Make sure you have a drip loop from your cords to your outlet though, dont want any mistakes there

a drip loop? Well the extension is in a place it shouldn't get wet. What's a drip loop?

isn't that when you droop the whole cable down and then bring it up before the outlet so the water drips off before it gets the the wall?
