Has anybody else noticed or read about an potential issue with the Trident testing? I run my tank on the higher side (alk 10, cal 465, mg 1500) and I have noticed that at noon my cal is 468 and at midnight it is 486. It has been like this for the past week (was set up November 18th). I have not been dosing for the past 1-1.5 weeks so I am not sure what is going on. I manually tested before setting up and everything was spot on so I continued dosing manually and was going to wait to set up automatic dosing until I knew the Trident was consistent and accurate. If I am not dosing, I do not understand why the cal would be fluctuating that much while alk has steady and very slowly been declining (was 9.95 dkh on 11/29 and is now 9.15)
