Need some help!
I sent water samples to ICP last week but didn't add the Sample numbers on the app to the sample tubes. I got an e-mail explaining the Proper way to do it and I followed the directions and replied to the email with the sample numbers.
I just got my results today and I'm thrown by the phosphorus reading. 179.73 ppb which if I convert using the Hanna conversion chart formula translates to 0.551?
I immediately tested my water with Salifert and that shows 0 to 0.03 (leans more to zero)
My Hanna ULR is showing 22ppb and 23 ppb on the two test I did. I haven't done a water change since I sent in the sample and I'm not running anything to reduce phosphates.
Any ideas?
I'm thinking my sample may have gotten mixed up when it was put aside. If not my salfert and Hanna are way off.
