Hey
I'm not too familiar wit ACRB
But have you tried putting the goo in the fridge after refreezing in the freezer?
Best is to maybe put freeze precip container upside down on a plate, so that if it oes melt it will be on the plate.
I know with MHRB, if you take it out the freezer, decant, and immediately put in the fridge for 2 or 3 hours, the crystals don't melt.
Its like, you don't wanna shock it from freezing to room temperature, you wanna gradually raise the temp from freezing to room by using the fridge as a middle step
Hope that might help

With every great plan comes the pleasure of patience. Take a rest, and grab a suckle off the teat of life!
