Question about power...

You can't just add a larger breaker and walk away unless the wiring in-wall is the proper gauge. You probably have 14g wire in your regular house wiring, which should only carry max ~1800 watts of electricity, and 1440 watts safely. It's mostly due to if you try and shove too many electrons down the wiring, it will overheat and cause potential fire issues. That's why you have a breaker in place, to prevent you from taking too much electricity down a certain gauge wire, by throwing in a 20A breaker, you're only endangering yourself.

A 'receptacle' constitues one plug-in, that you can plug one cord into. A typical wall box has two receptacles.

If you were worried about overloading the circuit, then just run a new dedicated 20A 12gauge line to the tank. If you plan on upgrading in the future run 2 x 20A breakers. You can split those into as many receptacles as you choose.

Cheers,

Nice thing about 2 separate circuits with specially with GFIs, is you're able to split the load so if one GFI was to trip, whole system doesn't crash. If the total load is okay on a single 15a cct, still can run separate GFI receptacles.

Another thing to consider is on a single 15A cct, you can have something like 12 devices (lights, plugs, etc). Depending on how things were wired, you might have your fridge on the same cct as your tank, them you plug in the vacuum down the hall, also possibly on the same cct. Sort of just plugging in a extension cord might not be any further ahead.

Running new dedicated 20A GFI-protected circuits is the best solution. Talk to an electrician about how much this would cost.

I have 3 dedicated circuits for my system: lights, pumps (on a battery backup), and everything else.

Im sure your fine with what you have. Im running my lights power heads pumps heaters fans ect as well as 2 computers tv large stereo more and more lights.

I also moved the treadmill over one day and the breaker only tripped when I was maxing out the treadmill with the stero pounding.

As others have said its prolly a good idea to get some sort of gfci protection in there.
*installing a gfci recepticle will protect everything else down the line from it.
*good idea to have it on 2 different circuits so if one trips youll still have some motion and or heat getting to the tank.

with your demand of 1440W you will be fine but are slightly pushing it and in even a small fault like a pump getting jammed it will draw larger than its highest current and could cause nusance trips,
a single duplex recepticle is both plugins they are usually on one circuit but in kitchens each plug on the duplex recepticle should be on a different circuit so you can plug the toaster 1400W and the kettle 1500W at the same time and not trip the breaker,
If you are worried contact a local electrician and have them quote a new run from the panel to your tank and install a GFCI for both circuits it could save your life in the event of a fault.
