I am having some trouble with my FC readings. I started a SLAM five days ago. First OCLT on 9/17 was 4.5 and in the morning it was 2.0. That is when I initiated a SLAM.
9/18 OCLT 22 PM 21 AM based on 10ml sample
9/19 24 PM 20 AM 5ml sample
9/20 30 PM 29 AM 5ml sample
9/21 26 PM 24 AM 5ml sample
9/22 21 PM 20 AM 5ml sample
Why do I keep passing and then failing? When I did the test on 9/19, I just eyeballed the sample water at the 5ml mark. Since it was such a small sample, I was worried I did not measure the water sample correctly, so the rest of the tests from 9/20 on, I would be using a 5ml sample and measured with the 1ml dropper to make sure I had exactly 5ml in the test sample. Water is crystal clear and CC is below 0.5. Do I continue with the SLAM or would you consider this done?
Also, I should add that after a full day of sun with 90 degree weather and SWG turned off, I would lose about 3ppm FC during the day. I think that probably sounds about normal for daily FC loss with full sun.
