I am currently planning for when I redo my tank in a couple of weeks. I'm looking at substrate currently and I'm torn between either going for JBL Aquabasis plus substrate and JBL Sansibar dark sand on top or whether to go for Flourite Black Sand.
My understanding, and please correct me if I'm wrong, is that the Flourite is all in and doesn't need an additional substrate underneath.
Does anyone have experience with either, or preferably both, options and advise which to go with. I'm swaying to the Flourite if it is an all in one as I am looking to have some sections of my tank raised.
