Does what it says!
I have tried other products not all but a fee and this is the only one thus far that has produces coralline in my tank not just the overflow box. It works as it promises without any negative side effects.

Very good product if you’re working on building coraline algae and overall stability
Great product! I’ve had great success with all products from Brightwell. This was no different and I was able to build some good coraline in all of my reef tanks. Easy to recommend!

Not sure if it works or not
I have been using this for about 3 months I am just now starting to see new growth on "Live rock". I am ot sure if it just started growing on its own or if this promoted the growth. My apology if this is not a helpful review. This is my first try at a saltwater reef tank and my first try at growing Coralline algae. I was told the "live rock would take off quick and I bought 2 of those. The first one "Petco" has nothing and the newest one (a fish supply store) only a few weeks old is growing Coralline like a champ! i used as directed.
