Yes, my corals look better and grow better, but there is a rather large caveat - previous to the FM salts, I was dosing supplements (Ca - seachem, Alk - Brightwell's) by hand. I started dosing the FM with a Profilux (so automatic doser) which is a lot more consistent (as I am not).
So I can't chalk it all up to FM, but I'm sure using their product doesn't hurt
