What would cause these two to be low???
Ph 8.2
Calcuim 375 mg

[fishieness]

probably the salt you are using and/or the amount of water changes you do
you also may not be able to raise them because your Mg may also be thrown off it if is yoru salt
what type of salt and how often do you do what sized water changes with what type of corals?
