Alkalinity does help keep your pH stable, but it's not a linear relationship between alk
and pH, as in if your alk
drops, so will your pH. Keeping alk
between about 7-11 dKH
will keep your pH stable, but the amount of co2
in the air in your house can push your pH down, regardless of what your alk
levels are. It's quite common the pH will drop in a tank during the winter in colder climate areas where the house is closed up and has less outside fresh air.
Depending on the type of corals are in a tank, alk
and calcium will be used up by hard corals and that may have to be dosed. It's probably best to check alk
and calcium more often than pH.
