thanks I checked the other forums on MFK and saw someone did PFS with black sand. nly one person posted pics and It looked okay. IIt was more white than black though. But since cost is a factor for me, will keep that in mind. I'd love to see it! thanksI actually re did the 75 gal with a mix of black and some of the older sand that was replaced by the garnet... the old sand wasnt white but looks like it after mixing it in with the black. I'll post a pic for you
