Bought this item to help set my CO2 levels as the API test doesn't go below 6.0 ph. Unfortunately, this item reads .6 ph high. My calibrated pen and AP test reads my pre-CO2 water at 6.4, this one tells me it's at 7.0. Returning.

Works just like the one I was replacing it with! Perfect! Keeps my indoor tower garden at the right ph levels so our family can have crisp, fresh, healthy produce all winter long in our house! No grocery shopping! That’s food safety and security!
