Alkalinity Question

Alright, Question time about alkalinity. This past summer my alkalinity, held in the 7-9 range with very minimal dosing. In the last few months it drops extremely fast. It will be in range and a in a couple weeks it will be down into the 5's. I raise it again and same thing.. I only test every couple of weeks, since all my other parameters hold so well. What causes it to drop so fast??

Current Tanks:
RSM 250 Mixed Reef
40B with 20L Sump Planning a Mixed Reef but undecided
