I have had this mound for sometime now and it has always done really good. Very good polyp extension and has always looked generally hardy. Well lately (past couple of days) the very bottom has bee turning to mush and very brown. The stuf sometimes comes off and where there was once polyps there is no more there. It swells up alot. I had puchased a Rose BTA and I think it touched it so I moved the "mound" and now this is happening.Thanks everyone
