I have never kept either the micro or macro solutions in the fridge. I do however use Glut-Metricide 14 in all my solutions. Keeping the micro's in the fridge is okay if you want to.
Sometimes it take a long time for all the particles to completely dissolve after mixing up a solution. Just shake the bottles well before dosing. It doesn't hurt at all if particles go into the tank as dry ferts can be used mixed with water or dry.
