so my ph is 7.8, so i bought seachem reefbuffer. Suppose to bring the ph up to 8.3 but my calcium and alkalinity are right where they are supposed to be. If alkalinity raises because of this should i raise calcium too?
If your Alkalinity is where you want it then low alkalinity isn't the reason PH is low. So, don't add more, it will just add one more problem to your tank.
Find out why it's low and then fix the problem, don't try to mask the problem by adding a buffer.
A few of the most common reasons:
High Carbon dioxide levels - insufficient waterflow, indoor air, malfunctioning skimmer.
High metabolic acids - accumulated detritus, dirty filter pads, overfeeding
