Does this stuff really work? Our local grain elevator has a jug that had dye, suspend technology, and bio (good bacteria) all in one. Does this stuff really work, or am I better off buying everything separately? I have had runoff this past winter/spring which has given my pond a tea/coffee color. I was wondering if these blue dyes with suspend technology actually work with taking the suspended particles down to the bottom? The elevator did not have any alum either.
Thank you
