FW exit a weird color.

Usually FW Exit is clear. This time its yellow. Did salifert change the formula? or did I get a bad batch?

Did it turn color after you dosed it? It could be the stuff the dead flatworms are letting out into your system. When I treated my tank I noticed as they died it went yellow. If that's the case, you definitely need to do a large water change ASAP - That stuff is deadly.
