Should I add more bleach before OCLT testing?

I've SLAMmed my pool, and am going to do the OCLT tonight. Here are the numbers I just got from testing:
FC=6.5
CC=0
CYA=30
pH=7.2
So my question is, do I need to add more chlorine to get back up to the SLAM level, or do I leave everything as it is since they're at the normal levels?

It sounds like you already let the FC fall below SLAM level for your CYA. We wouldn't reccomend that UNTIL water is crystal clear, CC is less than .5 AND. OCLT is less than 1
