Ammonia to use for fishless cylce

[mclife]

I was out looking for pure ammonia to do a fishless cylce. The best I could find has .15% Deceth-4 Phosphate. Seems like a very small amount. Am I safe using this ammonia to do my fishless cycle?

That substance is an emulsifying agent. Is there any other ingredients at all listed? And does it foam when you shake it (do the bubbles stay around for awhile like soap).

Yeah, i shook the bottle. The bubbles stick around. The only ingredients are ammonia, water, and Deceth-4 Phosphate.

If i can't use this, where on earth can I find pure ammonia?

I wouldn't use that stuff, though it will clean windows great. Around these parts (Nova Scotia) you can generally find the purer stuff in hardware stores. Sometimes it will have chelating agents but those are fine.
