Naw, 4 were floating with the new tester, so I should be good to -25. I didn't order the refractometer.Those are some interesting instructions, not much better than the floating pointer ones.
Were 2 balls floating or 4? would be my question based on those instructions.
If it were me, I'd either just replace the fluid with new or buy a magnetic heater pad if a block heater cant be added. Not sure the second one is any more trust worthy than the first, but you have a refractometer coming that measures the sugars, and as long as it is stored the right direction or you remember about the bubble, it will work well; and you can calibrate it!
