Can plants get nitrogen from NH3?
This may sound like an odd question, but I have done a fishless cycle on my tank, added plants at the end, and continue to add a bit of ammonia to the tank to keep the no3 up until I can decide on what fish to put in there and/or get my dry fert shipment. However, I really want to tear down the tank to cap the flourite with sand, because the flourite isn't making a very good cap for the mineralized soil i have under it and my water is always very cloudy. I will have to replace all the water, and I'm afraid that I will lose a good bit of my bacteria, and at the very least I'll be working with fresh water and it may take a bit of time to have the ammonia convert back to no3 for the plants to use. Can plants use ammonia as well in low concentrations or does it have to be no2/no3?
My main concern is that my java fern is not doing well, as I was an idiot and buried the roots for a couple days, and I'm afraid that the lack of nutrients will finish it off. All the big box pet stores around me carry is flourish, which to my knowledge is just trace elements, and the ferts at my lfs are crazy expensive so I want to use that as a last resort. My tap water has a bit of potassium and phosphates according to the water report for the city, but my testing kit shows that it carries 0 nitrates.
