Anyone ever used it, I just noticed this on the foster and smith website. I would love to convert my 75 gallon to planted but keep my black sand substrate because I like the way it looks. Would this probably be good to mix with my current sand (black tahitian moon sand) to do a low tech planted tank? Right now I have a thin layer of the tahitian moon sand in my tank and would love to be able to do this without completely tearing the tank down. I have enough lighting to be able to achieve about 2 watts per gallon so what do you think? Also what are some of the easiest care plants? I know java moss is really easy and good for the livebearers too. The current tank inhabitants are some platies and 6 or 7 small brig snails. Eventually I want to add a pearl gourami and maybe a school of cories and tetras, still planning the stocking because it used to be my fancy goldfish tank before I converted it to tropicals.
