I was thinking/researching the Sakrete stuff that had references to hardeners in it.
Ya, that's not it at all lol. I saw that stuff... But it looked more like concrete mix then sand, so I went with what looked most like sand. I'm actually really liking it though! I think it raised my PH! I went from about 6.6 to 7.6! Which makes me feel better. I'm also researching aquascaping... Thanks to Rook, I'm mastering the art of fukushiki! Lol. Still have the carbon running just in case, and the nasty filter media is in as well.
