I am ordering plants from online and they are all potted plants. I asked what I have to do to plant them and they said that I should remove the pots but leave the rock wool. I have been looking in the forums and most people say to remove the pots and the rock wool. So my question is should I remove it also or leave it. If I leave it in what will that do to my tank in long term. Right now the tank is empty but I do plan on putting fish in it after a week or two once the plants have settled in.
