Well after recalibrating my refractometer, i did the tests again in the morning and then at night (when the water was gone)
In the morning it was reading a perfect 1.025 ... in the evening it was at the most 1.0258 ... jsut under 1.026.
So i don't think that is a BAD swing .... i could be wrong and i am sure that i will be told if i am wrong
Thanks all
