Wayne - someone says "The Tahitian Moon stuff is basically finely crushed volcanic glass".... Also, the manufacturer says it won't alter the pH...
longtyme68 - I am still undecided, sure I want to use black sand so it reflects more color on my pretty Tetras... I will post pics once everything is set up (won't be till months later, as the tank is still brand new empty sitting here...)
Viciente - good point, thanks.
Others who is using this Moon sand please post me some reviews, I am still undecided... please help... Thank you all!
