When to slam ?

Is slamming only needed if my pool level is cloudy? I’ve always had cc of .5 in pool. Yesterday I bumped up the fc to 7.5. Today it’s down to 3.5 and my cc is now up to 1.5 . Water is clear but now I’m getting concerned. To be totally clear it was 7.5 in the morning. Last night I added roughly 2 cups 10% bleach and it’s still down to 3.5 with the cc rising. Should I do a slam ?

While that is one of the primary indications of algae, it's not the only one. We also look to see if a pool is losing more than 4 ppm of FC in 24 hrs, and you lost more than 4 ppm of FC (with added bleach). Your elevated CC level is also another clue. So I agree with 99 .... time to employ the SLAM Process.
