I give up. Even with 5:3 ratio mine is still crystallizing in my top feeder. I'm going with a 1:1 ratio, 4# sugar to 2 quarts (or more) of water, hoping to melt all the sugar crystals in the feeder. I used my hive tool to break up the crystals into small pieces hoping the warm, thin sugar water would/will melt the crystals.
why not just ad a little more water ? instead of going back to 1-1
