I am looking for a solutionwith regard to dosing in my new 130 gallon build. I am trying to avoid the problem of overdosing Kalk which has occurred a few times like when my skimmer decides to overflow causing my ato to add too much kalkwater resulting in a unwanted alk swing.I have a tunze now.and I have an apex.but when the tunze is off and restarts it adds about a cup of kalk each time.how can I dial this in for consistency?
