Well, it turns out those kits expired in 2011. I tried them anyway, though. Unfortunately, the bochet is so dark that you can't see any difference. I did more tests on a 10% solution but the high/low SO2 readings weren't consistent with each other. I don't know how accurate these things are, over a year past the expiration date.
I bought an oxygenation kit, thinking I could dispel some SO2. By the time the kit arrived, I opened the primary to find a thin layer of bubbles on the surface (the Uvaferm's been in there all this time). Perhaps it was a really long lag phase. I pumped in the O2 for 30 seconds, prepared a fresh EC-1118 starter, and poured it in. The next morning, the airlock was bubbling and still is two days later. The progress is still slow, though. The gravity has only changed about 0.006 since adding the un-caramelized honey but at least that's progress.
