I check and my alkalinity goes from 8.5 to 6
do you have a closed top or open top . can't forget about air/gas exchange
this could be the reason your readings drop

ok so that rules that out for now but you may still see a difference once windows start to open
sounds odd but it's true .
if everything seems happy I wouldn't be overly concerned about it just keep up on your reg water changes
mine fluctuates but I don't worry to much about it

Alk doesn’t drop due to gas exchange really. That’s more ph.

Figured it out it was because my magnesium was low. Dropped to like 1100 so was throwing off others
