While working on the tank, I felt a slight sting in my finger which I took as an electric charge. So I took a multimeter, stuck the red probe in the water and the black probe in the ground/3rd hole of the outlet. Sure enough, I got 30V on the multimeter!! I systematically turned off each electrical item in the tank but the multimeter never dropped to 0. Removing some pumps seems to drop or even increase the current but I'm assuming that they are acting as poor grounding probes when they are off which may explain why I see current dropping when I restore them... In any case, I'm very confused and worried that I may have a dangerous situation. I have a grounding probe which helps but obviously isn't the correction I'm looking for.

Hi Gang, Is anyone here an electrician? If so, I would like to speak to you about installing a couple outlets. Please PM me. Thanks! (BTW, I live in South Arlington) B

I'm beginning the install of a new tank very soon. I'm thinking I'll need an additional circuit, maybe 2. Are there some DO's and DO-NOT's with installing new power to a sump location in a fish room and to a display tank? Also, how much power is enough? Is there a good reason for having different things on two or more different circuits in case one blows so as to help save the tank? I'm going to have: 2 250W heaters in sump 1 150W heater in new saltwater vessel 1 250W LED install 1 Reeflo Blowhole 1450 (160W max) 2 Tunze 6095 powerheads (42W total) 1 CS1 skimmer with Sicce recirc pump (60W) 1 Feed pump for said skimmer plus a couple reactors (Eheim Compact + 2000) (35W) 1 Avast ATO (around 3W) 1 Swabbie (3W) 1 Apex (guessing 20-30W?) 3 small utility pumps for moving/mixing saltwater and RO/DI water around (60W total) So that's about 1300W total if everything was running all at once. That's well within the capacity of a 15A circuit, and since I have a bunch of 15A Romex, that's what I'm inclined to install with one outlet near the sump for the utility stuff and one outlet under the tank for powerheads and lights. Also, I know for safety it's good to have GFCI circuits. I'm not inclined to put that in the circuit box, but I'm hesitant to use it for the outlets either because I don't want to lose the entire power for the tank if something trips it. I could use a separate GFCI per device, but that seems kind of crazy too. I could always have two different outlets and put the critical stuff like the return pump and one of the heaters on a non-GFCI outlet and put the others on a GFCI outlet, I guess. What do most people do?
