SSS is used to denote how much white is on the shrimp. Seeing as how PRL/PBL can come in different grades (S, SS, SSS) I feel like the comparison is simply different. Others may view it differently though.
If I remember correctly I think the pure red line is the purest form of CRS meaning it hasn't been crossed with any other form of bee shrimp? The pure red line shrimp will usually have more solid vibrant color than regular CRS which also commands a higher price....I think lolI was wondering which is the highest grade of Crystal Red Shrimp?
The Pure Red Line or the SSS grade?
