Sand sub. Grow bacteria in dif tank?

[anonrider12]

Hi everyone, i have a 55 gl tank with a gravel substrate. I wanna take on yhe challege of plating this tank so my task is to switch to sand or sand like media. I really would like black for the color so any suggeztions would be much appreciated! So the guy at my lfs told me if i were to do that then my tank would basically go through a new cycle. So what i was think was basically cleaning the sand then cycleing it in a dif tank with the plants and such growing in it to basically growing the bacteria and growing the plants at the same time... Any thoughts and suggestions would be nice
