Hello, I have read alot about the relationship of PH and Alkalinity. It seems that for the most part if your ph is low so is the alkalinity and vise versa. My proplem is that my ph is a little low at 7.8 and the Alk is high at 7.0meq. I read about using buffers or different things to lower the alkaline but they all seem to lower the ph as well. Is there something I can do to just lower the alkalinity level?? All my other readings are good: ammonia-0, nitrite-.2, nitrate-0, salinity 1.025, 60lbs live rock in a 60gal and about 73-75deg. thanks!!
