you need to keep dosing...how much depends on how much nitrate you have, the aim is to balance the dose as accurately as possible to the need. Too much produces bacterial slime..too little and the nitrate level will rise. Change your feeding regime and you can change your nitrate position and required carbon dosing (Nopox)...test adjust..test..adjust..small changes ...big patience
While Red Sea claim Nopox will reduce phosphates as effectively I have never achieved this and like many others, run a phosphate adsorber as well as Nopox dosing
