If you want to get rid of the dark coloration, I suggest you fill a box filter with activated carbon, and slip it into the tank. It wil clear it up for you nicely. As for the popularity of peat, it is simple, effective, and reliable. Lots of people are using it, including some small-operation discus breeders. When the size of the operation gets bigger, most folks find it more efficient to use RO or DI.
