Is 3M Colorquartz "T" Grade bad for Clown Loaches?

I have S grade 3M with no problems for my loach, he's around 5-6 inches.

its a little more abrasive then the S grade but i think they would be ok...

personally, i would just stick with the S grade..

I'm with DeathSting. I got 'S' grade specifically because I've got a lot of Loaches and other bottom feeders in my tanks. The lady at the store said the 'T' grade was angular and had sharp edges.
