After using it on over a dozen different frags, LPS and SPS (no softies tried) I have been quite impressed. Any pests dive off the corals immediately and drop dead. It also appears to be much easier on the corals, especially the SPS dipped so far. Surprisingly, no excessive sliming or polyp retraction has been observed as can happen with some iodine treatments and some LPS have even extended their feeder tentacles while in the dip. So far, no experience using it to treat sick corals (thank goodness) so I am unable to give my impressions concerning this use but I have no reasons to doubt the manufactures claims.
Being overly cautious with dips, I have only mixed it 1/2 strength or so and it’s working as advertised at that concentration. ReVive is what I will use from now on as a preventive dip, it’s cheap and a bottle will last you a lifetime. Available from the majority of online merchants and in my LFS. Iodine (lugols, ect.) definitely has its place but for routine preventive dips, ReVive is a good alternative.
I give it 9 out of 10 (haven’t seen a 10 yet)
