How to ensure I'm not over dosing?
Hello, I am worried about over dosing my small 2.5g (estimated 2g water volume) tank.
Assuming no uptake by my moderately planted tank I estimated my ppm of Potassium to be 4.82ppm after my last water change. So I added an amount of Flourish Potassium to raise the ppm to about 22.82ppm. My next water change is coming up and I'm not sure how much to dose. My plants are seeing heavy growth, recently though and I do hear of people dosing 20ppm weekly. As in that seems to be a pretty normal thing I hear people do.
Also, if I have flourish Comprehensive that has trace elements do I need flourish trace as well? I hear sometimes yes and sometimes people say no.
