Worked very well for me
I added this and scraped some coralline off a few snails into my 220 gal tank. I was able to tell a noticeable difference. Certainly faster growth in many spots than I had seen in my 150 and 180 tanks previously when not using it.

though it works well, it also seems to activate on living tissues
