OkI have looked all over Wal-Mart K-Mart an most all grocery stores. I have found calgon in the stores, butother than what most DWs would put in a hot tub of water and soak. Can someone give me a exact name of what Ishould belooking for. I know in a passed thread I stated I have already winterized the MH, but I still would like to used the calgon in both gray and black tanks and willing to de-winterized if I have to. Thanks, Hollis
