Every OUTLET in house, Deck, Bathroom (if wired Properly by a qualified Electrician) will go to same GROUND.@wallyim what GFCI outlet do you recommend? Link? Im in an upstairs apartment so I cant really modify anything or change breakers. Also should i put a ground probe in my sump and display? Im sure I only need it in my sump but just thought I'd ask. Last question. Do I plug the ground probe straight into the wall or do I plug it into the GFCI out let and then my apex and everything else into the GFCI outlet as well? Thanks. Sorry for all the questions.
Im glad you are alive to teach others from this experience. I've only been reefing 3 years and have never really thought a ground probe or GFCI was "that important". Thank you from opening my eyes. I will make sure all of my reefing buds get ground probes and GFCI on their tanks if I have to buy it myself and physically install it on their tanks myself!
So every outlet will work with a Ground Probe.
But best to be safe and put your Ground Probe on the Same Outlet as your tank is running.
Best to not put into a power bar since that is just another point of unnecessary Failure.
I can't recommend what GFCI outlet to buy, but I will say, don't go buy something from Aliexpress China.
Buy Name brand like Levtron.
Most have LEDS' and some of the better ones "I read" constant Self Testing.
Best to Test yourself by pushing the TEST button.
GOOD QUESTION (Sump or Display)
I have probes in both, but not all 3 of my setups.
It's about protecting you and not fish.
So while yout tank id running and water flowing between tank and sump. Both are protected while water joins both.
If you turn off Return pump, and hose dries out a bit, they are disconnected, so the one with Probe is more protected.
And of course it matters where you have High Voltage AC.
If you have Low 12 volt DC pumps in tank. No need for probe unless your AC light fixture drops in.
Best to put the Probe where Heater is, since they are all AC, and they fail eventually, or can crack by mistake since glass..
