I'm going to be using Tropica fertilizer, If my water is 40ppm Nitrate do I need the specialised which contains nitrate or go with the premium which doesn't have nitrate?
not quite sure what you meanI don't know if could work. But I would be on it with the water changes because it could lead to an un heathly tank.
Do I need to dose N&P if my tap water already has 40ppm nitrate?
