Hi, just wanted to know why my xenia exploded... at first it was ok, i decided to raise the PH because the level was under 8.3, so then i mixed about three teaspoons of buffer to half gallon, i poured it to the stream near the powerheads. Next thing the xenia began to get bloated and finally ripped!! Today my xenia is decolored and has no signs of life. What was wrong with the process? Should I raise PH more slowly??? Well at least I still have my devilhand...hehe!!
