After about a month of testing a vinegar and sugar syrup for feeding my bees, I have made some revisions to my formula. I noticed that if I added too much vinegar, it did not kill the bees, but it did discourage them from eating the syrup. At first I tried 1 cup of 5% acidity (50 grain) distilled white vinegar in 1 gallon of sugar syrup. However, after further experimentation and observation, I found that between ½ and ¾ cup per 1 gallon of sugar syrup is ideal. Just replace the ½ or ¾ cup of the water in your sugar syrup with the vinegar (1:1).
I had been adding a tablespoon of white vinegar per gallon but recently read everyone is using apple cider vinegar to prevent mold. I'm also wanting to adjust the PH.
I'm working on making up my own HBH/ProHealth.
The girls had some bad dysentery this winter.
Citric acid and Ascorbic acid are other ways to reduce the PH
