Hi, just wondering if any of you think this is a stupid idea or not? I will be setting up a new 5ft tank in the near future that will be heavily planted with plenty of wood and rocks. I was thinking a bottom layer of aqua soil then laying a sheet of filter floss over that before capping with sand. Would have thought the floss would act as a great anchor for the plants roots and give a little protection to the aquarium from the heavy rocks, but don't know if the floss in the substrate would cause any issues other than if I wanted to uproot plants. Opinions and advice very much appreciated
