That was quick! OK, so with a CYA of 40 you are over-chlorinating during your SLAM. While there is no real harm this particular time, the ranges we suggest are always there for a reason. You are wasting a significant amount of chlorine.
Please let your FC drift on down to around 16 ppm and then hold it there just as you have been holding around 30 ppm until now.
While we love folks who test often, the looks of your improving water and your results indicate you should reduce your testing to 2-3 times in a 24 hour period. Easier on you and no harm to your SLAM process.
You are close to done. Stay the course and be sure to remember the three things that will tell you your SLAM is complete.
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.
