There is a variety of sand known as Fiji black sand .I think it is composed of araganite and volcanic rock .. ..Caribsea Tropical Isle Tahitian Moon doesn't affect ph so I apt to guess it has no real buffering capacity . If you are changing water on a good schedule that should help with buffering ..check it out via www.caribsea.com
