Yep that's the one I used. Worked like a charm. Only took one treatment. Just as a heads up, you will notice on the back it will say "no need for water changes" I did a 20% 2 days after using it (once you don't see any slime) the guy at the lfs told me that just because it's not on your live rock/sand, doesn't mean it's not floating around in your tank. Good luck!
