I've started cycling my new 40g tank. I feel like it's taking a while, but that's not my main question. When I bought the ammonia, I made sure to get clear unscented, and the only ingredient listed is ammonium hydroxide. I thought it was good since it didn't list surfactant. But I just shook the bottle out of curiosity, and there were some bubbles around the edges that didn't go away. It's not fizzy or anything, but I heard bubbles mean it's not suitable for cycling? If I have the wrong ammonia will I have to clean out the whole tank or just get the right kind and keep going? If there was surfactant aren't they obligated to list it in the ingredients?
