Aquarium Advice Regular
I am doing a fish in cycle, I am 2 weeks in my ammoinia is nearly 0 but 3 days ago my nitrites spiked to 3.3 mg/L. I tested nitrates last night and I got a 110mg/L reading. This seems strange I did a water change last night and this morning I got the same reading. The fish seem fine at the moment.I want to know if this is normal or if I have a problem.
