1. I use a mag float. Frequency depends on my use of Vibrant, if I dose Vibrant, less than once a week for minor cleaning. If no Vibrant (as I'm doing now) I clean it once a day before film starts to build.
I use a Flipper Nano for my main tank and a set of 3 brushes from Marina to clean the nooks and crannies and my refugium walls. I still have a old bottle of Coralife glass cleaner and polish to clean the outside. That stuff is great! I wish they still made it but I believe they don't. I heard Kent Marine took it over and that is the same stuff as the Coralife.
