Talk:The Corruption/@comment-66.229.104.56-20111226181503

Would someone be kind enough to elaborate on the differences between "Purification Powder" and "Holy Water" when it comes to erasing corruption? Ours keeps spreading, seemingly because it is creeping along underground - our underground Hallow is really enveloping the map too. Building long walls/shafts may help, but aren't they for naught if even a block or two of pearl/ebon are mixed in with your normal dirt on the other side of your divider? What a hassle to try to get a visual on every single block!
