another thought, the test kit is new to you (6months) but could have sat on the store shelf for ages. double check the expiration dates on the bottles/kit just in case.
a little stumped otherwise. unless you were putting in water that was over 10 degrees hotter/colder than your current temp, or not conditioning the water (which you are), i'm not sure what could be causing it.
doesn't seem like it's a water issue though as your other tanks would be using the same source with no issues.
