Well, the interesting thing was that the float was completely askew, only one small edge of the float was touching the bottom of the float box. When I touched it, it moved easily. I too wondered if I had boiled down to the point of the float sticking to the bottom of the box, but it doesn't appear so...but thanks Clinkis, I will definitely keep an eye on that.
To resolve the problem, I did something that now appears strange. I drew some 20gals of "nearup" (maybe 30-40 brix) off the arch and dropped it into my storage sump. That promptly changed the color of the tank the sump pumps into, and the manifold that comes off the bottom of each tank. I tried drawing off into my OMG pail, like 10 times, hoping the color of the sap would lighten...it didn't....;-] So right now it looks like I am feeding my arch with a light amber sap....?? In any event, I boiled for 6 hours today and got my front pan back to +8, then I shut down. I wanted to shut down early so I could check Clinkis' idea. So far, the pan level is not rising and the boil is gone. Later I will be putting a piece of plywood covering the float box. Unfortunately, it means I boiled some 40 gals with no draw...so much for my 12:1 ratio.
I have to say, I don't get you guys and your aversion to flies. So a fly (or 100 flies) get into your sap, that's what filters are for. If you find them revolting, I just want you to consider how many animals have peed around your maple trees, pee which seeps down to the roots and...becomes sap. As maple syrup producers we should embrace the nature that gives us this nectar. Also remember how prosciutto is made...hams are hung to be infested by flies laying eggs...when enough have laid eggs, the ham is then smoked...I'm just saying...like everything else in our bushes, flies serve a definite purpose and should be embraced for the job they do, and if we happen to kill a few in our sap buckets...sorry flies, but I'm not throwing anything out because of it...;-]
