It took a week to dial in and I have not changed it. I wipe down the neck every week to help with any build up but I have gone 2 weeks with a lighter bioload. The main issue is to keep the pumps clean internally from collecting any precipitation of mineral. If my water level changes in the skimmer, I know it's time to clean the BB pump or sometimes the sump to skimmer pump which is an Eheim 1262. The drainage cup drains into my adjacent work sink so that helps a great deal as well. Adding Kalkwasser in addition to CaCl and soda ash, I clean the BB in HCl about every 2 months for optimal performance. It is easy to swap out a BB 10k for my spare with a water change and then break down and clean the original pump.
