I started dry fertilizing this week. Did my regular water change on Sunday and dosed for the first time on Monday. Before dosing, my NO3 reading was about 5ppm. It's now Wednesday, I did a water peraminter check and the NO3 readings are 50ppm.
I used 3/4 tea spoon and its a 75 gallon tank.
Should I keep dosing or wait until the levels go down?
Also, I have no way to check the (K) or (P) so I am assuming these would not be ff the chart too!
Is this normal?
