So I just ordered a gallon of bicarbonate. I hope this works. My whole display has a white film on the glass from precipitation. I cleaned it all off with a razor. 2 hrs later looks like I never cleaned it. I just read your whole article on precipitation and what causes it. My ph is around 8.5 before I dose. So it must be the high ph that causing the precipitation. Do you think if I vinegar dose will help with this. Or should I just add some arm and hammer baking soda to help out till my delivery comes. I don't know what I'm going to do with all this soda ash I have left over. I have like 3-4 gallons. Maybe I could mix the 2. Would that help out if I mix them both. And what would be the ratio for that.
