With everything, comes a 'it depends' caveat
7 is the alk number I strive for, but I'm running Zeovit and that's where ideally I should be close to.
Can you dose things out of balance, yes. Majorly out of balance, no -- things will start to precipitate out if you are significantly out of balance and then you might start going the wrong direction.
My biggest question is: is there something that seems not healthy, or not 'right' in your tank that you are looking to solve? Or are you just trying to chase a certain number of Alk?
Also, have you compared your test kits with that from another reefer?
