Too add or not to add

[exotics]

My calcium is at 480 and really is stable and my alk is at 3.5meq but I see the chart states that alk should be at about 6 meq. So should I dose something or not.I have never and still do not dose anything at all in my tank.Please let me know. I do have kalkwasser mix and kent tech CB part A and Part B on hand though.thanks Bill

IMO, your readings are fine. Does the alk stay stable around 3.5 ? If you just started testing alk. then how stable has your pH been ?
