I don't think the haze is from the low alkalinity - it isn't very low, you want alk to be between 80 - 120. You can add baking soda to bring up the alk - it may bring up the ph a little, but that would be ok. Using baking soda will raise the alkalinity and the ph may raise just a little' - then you can add acid to take the ph down - it won't effect the alk much. When you want to raise just the ph you add borax, it won't raise the alkalinity. Hope this helps, ask any questions you may have.
