For less than $3, you can't go wrong with this! My corals are so happy now. The only drawback is that for the size of my tank, I used about 1/3 of the bottle in each dosing. Wish it came in a larger size, or that it could be concentrated a little more.
I bought 2 bottles of this at a local Mom and Pop store and used as directed. Really wanted to get coralline algae going, bought 4 more on line and nothing. The deliveries arrived packaged differently, one taped shut, two more with Chewy tape on them, the two from amazon came sealed in amazon bags. What am I buying for $75. I did nothing for my Coralline. I have nothing to show but empty bottles.
Noticed that the coraline algae wasn't coming back as usual, tried this supplement and it's getting back to normal and spreading after 3 weeks!
