I have the Hanna Alkalinity Checker. I noticed that after I open a new bottle of reagent, my alkalinity goes up. Over the course of the last week my alkalinity was bouncing between 7.9 and 8.0. Last test was Saturday. Open a new bottle this morning(I test every 2-3 days) and my alkalinity is 9.0. Ran the test twice on my 75 gallon tank. So I go to my BioCube(2nd tank) and test. Sure enough what was 8.8 on Saturday is now 9.9 this morning.
Anyone else run into this? Let me know if you have.
I shake the bottle before drawing out the reagent. I do not put the left over reagent back into the bottle.
