Hi all, I am thinking of doing live plants in my tank. I am doing a DIY light with 2 40 watt lights T12 size with 8 blue LED for moonlight, as a reflector I am mounting a mirror on the enclosure, can I do low light plants with that set up? Also I would like to do sand for substrate (Quikerete medium sand) I know I need peet moss and something else layed under the sand I just do not know how much?
