I am in no way an expert but speaking from my experience with it I would not recommend it. Here are my reasons, which may not be the same for everyone, but again, speaking from my experience.
* It is horribly messy. I rinsed mine forever and even with a ton of it ending up down the drain it still left a mess all over my tank and in my filter for a long time.
* Plants do not like to stay in it. I put a layer of CaribSea Floramax in my tank at first and thought it would be too rough for the Dwarf Corys I wanted to get so I then put some black Flourite Sand on top. Needless to say the Cobamba I bought didn't stay in the tank long because it was constantly floating all over the tank making a mess. The Flourite Sand is VERY fine, almost powdery. I think the only reason my Vals stay down is because they've made it down to the Floramax.
* It doesn't look black! Maybe it's just my tank but it looks like a gray color, even after the white layer of filth on top eventually went away. I am currently using Tahitian Moon Black Sand in some of my other tanks and the plants stay down, even the stem plants, and things are growing just fine even with no ferts and low light, and it's a very beautiful shiny black. I will give the Flourite Sand one thing, it does look very natural in my opinion.
* Last but certainly not least, it's way too expensive in my opinion for what you get.
Sorry to be such a negative nancy but if I could do it over again I wouldn't have purchased the Flourite Sand.
