Yes you are correct and I would only run 14-2 from the switch to the light

If that is behind sheetrock or a wall still use 12-2.
Only a UL specified equipment from the wall outlet can be used less, like a lamp or radio.
Sometimes they will have wires as low as 18-2 but they are UL tested and you should be good.

No I'm talking like in the attic

My 28 gallon shocks me if I don't have shoes on lol

I had the same issue with my nanocube. I invested in a grounding probe and the shock therapy was over.

Job well done as it is a fact and part of the national code that a 20 amp circuit must be at least 12 gauge wire.
Theoretically, all building codes were designed to protect the next owner (or renter), not you.
Laws are meant to protect others from our actions, not to protect us from our own decisions.
If all you are ever going to do is plug in a light bulb, any wire will handle that current.
What about the next owner though? If they want to add an outlet, they shouldn't have to worry about whether you saved a buck by using 14/2 instead of 12/2.
The part that will be visible to them is the 20 amp breaker.
If the code is followed, the future owner will know that if they follow the same rules, there will be no safety concerns.
However, if you deviate from the code, the future owners could follow code in their new work and unknowingly create a dangerous situation through no fault of their own.

Not to mention an animal chewing through a wire and shorting it, or a nail through a wire, or any other accidental short. Breakers are rated on how much power can be pulled through a wire before it gets too hot and melts/catches fire. They arnt just there for the next owner they are a real saftey device and improperly sized ones can burn a house down...

No I'm talking like in the attic

So theoretically, lets say you used 12-2 to the room, then branched 14-2 off that but still used a 20a breaker, if an animal, a nail goes through that wire or that 14-2 wire shorts for ANY reason, your breaker isnt going to pop til its over 20 amps, and by that time that wires melted and could possibly catch fire.
If you ran 14-2 off the 12-2 i would switch that circuit to a 15 amp breaker or replace the 14-2 wire with 12-2 to be safe.
If the house burns down and they find that 14-2 in the attic as the cause, and found out you did it, guess what? Insurance isnt paying for it.

I called Tunze regarding this with their wave box because I heard the same thing. Their response, don't quote me (it was 2 years ago), but it's something like this:

It does decrease the lifespan of the tank by 10 to 15%. He recommended using the wave box on a tank that was made under standard specifications (then noted that all major tank manufactures use the same minimum guidelines). Under these standard specifications a tanks life span is 17 to 20 years. So he said at most you'd be looking at decreasing your tanks life expectancy by around 3 years. I doubt I'll keep my current tank for longer than 10 years.
