Yeah the filling works like a toilet bowl float kinda. If you put a bit extra in there I wouldn’t worry to much. The next drain and fill will bring the water level to where it should be. From that point forward use the fill option in the app and if does or doesn’t take any water you’re good.
Now the glass, I don’t surgar coat things. You need to bug them until they send you a new door or fix the one you have. It looks unacceptable to me. Some more constructive critism is who ever assembles those glass components maybe in China, is doing a terrible job and they need to get better QA controls on that ASAP. My seal around my glass in a smal area is cosmetically ugly. It just got brushed off and I just sucked it up but I’m still not satisfied with it. It doesn’t impact anything on the growing so I sucked it up, that’s not the point. They need to fix that crap, rant over, LoL.
