         I had layerite (sp?) and onyx gravel along with regular gravel. 
About 9 months ago I removed most of the gravel and tried to leave behind 
everything else.  Replaced it with play sand from Lowes, even after rinsing 
it, it clouded up the tank and plugged the filters for months.  It is just

wasn't doing anything in the gravel, has almost covered all the bottom of 
the tank now.  There are some expensive sands available which say they have 
all kinds of minerals and such plants need.  I haven't felt the need to 
spend $30+ for a bag of sand..
         I won't claim to be a expert on it, but I am setting up a new 29 
gallon tank and I am going to do a layer of fluorite and then some sand 
(bought two 50 pound bags), still have one left and the first was more than 
enough for my 44 gallon corner tank at least 2" thick.  It will be all in
