How can you successfully replace your substrate in your current tank without killing any fish or causing your tank to cycle again? I'm planning to replace my regular substrate with ones that are meant for plants. Anyone has experience with this? How did you do it? Did you take all the fish out? Is it a good idea to just put it on top of the old substrate? Thanks.
