Hey all, I am fishless cycling my 75 gal
tank. I'm into day five and my amonia, and nitrites are zero. But my nitrates won't go down. I did a 25% water change, and I checked my permitters and no change. So I did a 50% water change and still no change. The only thing I did today was add plants and plant food and now my nitrates are stuck at 40ppm will
My cycle and kill the plants?
Thanks for the help
