What do you dose?

Well it looks like we have quite a few high hat wizards here. You guys and all your potions...im currently running 2 part. What if any depletion of major or minor elements have you guys recorded in terms of typically 2 part use. Im sure various tanks will have different results due to livestock but im curious to know from a swath of users. D Did the AFR route in a past tank. Mag always seemed a bit low. I can't recall the amount I was dosing at the time but I did notice an increase in salinity over a 2 weeks dosing schedule. This was for an 80 with 20 sump.
