So I did a 90% water change yesterday morning. I noticed that it started getting cloudy again last night. This morning the water wasn't any cloudier but when I tested the water the nitrate was 0 but the ammonia was really high. It was at 8 ppm. My tank and my room smelled like ammonia
I emptied out the water and plants. Pulled all the osmocote I could find. Rinsed the substrate 3 times and then put back the plants refilled the tank. I tested the water again before I left for work. It was between 0.25-0.5ppm. I'm going test the water again when I get back from work.
Currently, I don't have any fish in the tank. Just plants. Do you think having the ammonia at 0.25-05ppm is ok? And if I do add a betta would the ammonia have be at 0 before I add him/her?
