That depends. If it is silicates, let it alone and it will burn out. No other way around diatoms.
If it is cyanobacteria, this stuff consumes the same stuff that the nuisance algaes eat. So, to lower nitrates and phosphates you want to ensure you are using ro
water, feeding sparingly (I only feed my 55 reef tank half a cube of mysis three times a week for example and it might be too much), and ensure you are doing 10% water changes weekly. Your system may also be one that could benefit from types of filtration like GFO
, that remove phosphates...but that is for a way more extreme end of things and not something to be considered unless there are issues.
