Moving a reef tank

[Xblackout]

Hey, so as I stated in a previous post, I'm buying a 180 gallon reef tank from someone who lives 3 hours away. My question today is do I need to be worried about the coraline that has grown on the back of the tank? Should I scrub it all off before refilling it with water?

i like it. i dont know about others, i assume it depends upon individual taste. they are not pest, but they'll consume alk/Ca. If the tank will be dry for prolonged period, then its worth scrubbing
