Staci, very happy to see the progress. Try not to let the testing overwhelm you. Easy stuff. You can ignore the pH test still. Throughout today, continue with your SLAM number like you have been, maintaining that FC of 35. The sun goes down a bit early now, so wait before going to bed, take one last FC test using the FAD-DPD tester to get an accurate result. Since you are still technically in the SLAM, your FC should be 35 at that point (bedtime). When you wake up, test immediately before the sun hits the water. You do not want to lose anymore than 1 FC by morning or else the OCLT failed and you continue the SLAM.
Now keep this in mind .... your water is blue which is great, but it's still cloudy which means it is still working to kill organics or filter-out the dead stuff. So if the water isn't so clear that you can see the bottom really well, then you may want to wait another day or two before attempting the OCLT. It's usually the very last step in the SLAM. It's up to you though. I just don't want you to be too disappointed or waste anymore R-0871 drops than you need. Best of luck to you, and have a nice weekend.
