hello fellow reefers, I've been having some alk issues in my system(29 w/80lbs LR w/20gal sump&refuge), and I tested alk yesterday, and it was at 5.4. In desparation and panic I dumped a whole teaspoon of baking soda to the system just after I did a water change; smaller than normal(5gal). Well to get to it my alk is at a whopping 16! I need some advice as to what to do here about this, or if there is even a problem with numbers at this level, and my calcium by the way was at a high 600. Thanks for input.
