The sugar content does increase when you remove ice. I let my storage bins skim over, and remove the ice each morning. My sugar ccontent went from 2% to 3% after doing it a couple times.
Im considering thawing my buckets enough to get the solid chunks out, letting it skim over in the pan, and skimming off the ice for the next few days, but its a lot of screwing around to thaw them out. I have a few buckets that are going to overflow when it starts running that i'd like to empty at the very least. We'll see how ambitious I am over the next couple days. Perchin tomorrow, but off wed with no real plans. Lol
