"THE ALL POWERFUL Q !!
this stuff is better then tahitian moon sand and cheaper too. i pay 20.00/50lb bag. my fish love to dig in it and its safe for them. it comes in a fine "s" grade like beach sand just heavier since it is quartz with a ceramic coating. it also comes in "t" grade which is little bigger and coarser but the bigger fish enjoy this too.
