Hey. I am a newbie to this hobby, and I've had this 90 gallon tank for more than 2 months. The nitrates in the tank water is around 40ppm (saltwater), the water that I add to the tank is around 0ppm (freshwater). The phosphates in the tank water is around 0 ppm. I did not test the phosphates on the water that I add. Can someone more experienced tell me why the nitrates are high and the phosphates are low?
Also take into consideration.
