a question if I may Please? I have been dosing for over 150 day and nitrates have dropped to a nice level. now starting to get cyano on sand bed so I started to add some MB7 and change my carbon source (from vodka to vinegar) Cyano doesn't seem to want to go away. How can I use red slime remover when you need to shut down your skimmer, not a good thing to do if dosing. Do I add an air stone in it's place?
