Martini Phosphate Colorimeter
I just bought this colorimeter and I can't get any reading but 0.00. I tried reef tank water, newly made saltwater (Oceanpure), tap water. All 0.00. Everything seems to calibrate fine and no error messages, etc., as per the manual.
Anyway, I just don't believe my phosphates are zero. Any ideas? Thanks. |
