Sand

Anybody know where I can buy aragonite sand off the internet for cheap (postage aswell). My lfs sells it at a little under £30 which i thinks a bit steep

Go to your local garden store (or wherever they sell playsand) and bring with you a few small disposable cups (like 3-4oz in size) and a thermos of vinegar and water (1/2 and 1/2 mix). Take a sample of a sand, put it in the cup. Add a splash of water/vinegar. If after 1 minute the sand is still bubbling/fizzing, then it is aragonite. If after one minute, it is NOT bubbling/fizzing, then it's silica.

I just bought bags of ARAGONITE CORAL GRAVEL by Underworld 4kgs. For my Nano £4 ea. 3 bags (£12) was enough to cover the base 24"x12" to a depth of 2"

would 16kg be enough for a 20 uk gallon?

Plenty, probaby too much. What's the footprint (bottom dimensions) of your tank?
