So I just got my new hanna checkers and when I tested the phospahte url the test came back.90 color blue Yikes?
I then tested with api and I think it reads .25 - .50 very lite green. So what am I missing here? I ran three test with the hanna all the same
out of range I guess. I put some phosband in the HOB refuge about three days ago and nothing. What can I do?
