shouldn't fall that quickly, how often do you water change? What is your alk
now? Also it would be handy to know your PH
level (& what time of day you took the reading) & also your calcium level as they are all interlinked
The best way to tell is to test the alk
a couple of hours after a water change & then again just before you do the next water change & see how much its dropped, then you'll know whether a little buffer is required in between....
