I used a GFCI circuit breaker and regular plugs for mine. But I ran whole new circuit dedicated to the tank. The only drawback to using a GFCI circuit breaker instead of independent GFCI plugs, is that if the breaker trips I lose power to EVERYTHING.

It's only tripped once, when I plugged a pump in. I cleaned the plug and socket, reset the breaker and everythings worked fine since.

My whirlpool bath has a GFCI breaker also.
