I am currently doing the "Fishless Cycle" on a small 5.5 gal tank. The cycle seems to be going pretty good. I had the ammonia spike to 6ppm or higher and now the Nitrite and Nitrate are spiking and the ammonia is 0ppm now. So it seems to be going good. But my question is.... I believe the ammonia I used was not 100% pure. I realized tonight that it if I shake it it will bubble/foam a bit. It is clear, it looks like water and it doesn't seem to have any perfume smell. How will this effect the water? Will I have to start the cycle over again with proper ammonia or will it be ok?
