Now it's about 10ppm nitrate and I want to lower it to about 2ppm. So it's not that much, and I like to adjust the value quite slow. You will notice bacteria growth if you add higher amounts of carbon source, and too much bacteria bloom might lead to lack of oxygen in the tank. So therefor I think it's a good idea to start with a low dose and increase slowly to find the right amount of carbon source for a tank.
