Hello - Advice needed

I bought a 5.5g and want at least 3" of substrate bed.
Im debating on:
3 liter bag of ADA New Amazonia - $27.69 shipped
9 liter bag of ADA New Amazonia - $52.04 shipped
22 lb bag of Up Aqua Soil - $41.00 shipped
Has anyone tried or reviewed Up Aqua soil yet? Seems to be my best investment option..
