For review, here are the three criteria for finishing a SLAM...
1. Your Pool water is crystal clear with no visible sign of algae
2. You passed the OCLT losing not more than 1 ppm of FC
3. Your CC's test is either .5 ppm or 0 ppm.
So, the only questionable item is the "crystal clear" part, right? From you pic, your water looks crystal clear to me. I would let the FC drift down to maintenance level and call it done.
I would also suggest running that VS pump 24/7 at low speed if you are not doing so already.
