So I've started dosing Core 7. I cut holes in the top of the bottles and dose directly out of them with a doser. I've noticed that 3 of the bottles are about 1/2 gone while the 3a bottle is 1/4 or less left. The hole in top on this bottle is bigger. Is this prone to extra evaporation? I've checked my dosing calibration and it is all on point. Also, my calcium is around 390, my alk is at 7.9-8.0, and my Mag is around 1350.
