I am dripping kalk 24 hours a day to replace water lost and have a PH in the range of 8.65 to 8.40, Calc is 440 and alk is 9.6, what problems exist with keeping PH above 8.4 range ? Planning to add more distill vinegar with top off water to help bring PH down, anything else I should be doing?

More aeration should drive the pH down. Does the system have a skimmer?
