Andrew, just wanted to make sure that it's extra clear-
20 gallon tank: 1- 2 liter bag POWER SAND and 1- 9 liter bag AQUA SOIL
The two products really need to be used together to fully maximize the benefits of the system. AQUA SOIL was not designed to be used by itself.
Total cost to do a 20 gallon tank using the POWER SAND "SPECIAL" which saves you the additional purchase of CLEAR SUPER and BACTER 100:
1- 2 liter POWER SAND SPECIAL "S" (small granule)- $19
1- 9 liter AQUA SOIL- $22
TOTAL: $41.00 + shipping from Houston,TX 77027 to your address.
You may estimate shipping by doing a mock order (just don't complete checkout if you're not ready) at www.aquariumdesigngroup.com
