So your local pool supply store was able to set you up with this stuff? Mine said the only thing they carry is pool filter sand. Stupid pool store...
Anyways, the S grade is finer than the T grade. If you have soft-bellied fish, then you'll probably want the S grade, otherwise either should look good. And honestly, even the T grade is probably fine for soft bellies, it just gives a slightly rougher look to the sand.
