I've started using phosguuard to remove phosphates from my tank since my tap water has phosoah. The main reason I started doing this is because my tank has had diatmos (brown algae) for the 4 years it has been running. Now that I am keeping phosphates at 0, will the diatoms disappear on their own or will I have to scrub it off?
