types of substrate

[caffboy]

i'm in the process of transfering my 90g to a 180g and wanted to get some ideas or feedback on what type of sand to use as a substrate that could be seeded with my current live sand .

I love ultra fine grade sand. ordered 40 pounds of it looks like powdered sugar.

If you are gonna buy good sand, go with caribsea seaflor special grade. If you do the math on the price difference and pound difference, it's only .01 cent more per pound than the aggromax sugar sand. If you run a lot of currunt in your tank it won't blow around like the aggromax will. Both are great substrate though, just a difference in grain size. The Seaflor is a much more natural look.
