I bought the $32 kit for testing and so far have not located any ammonia. Will probably go out again searching tomorrow. Question: I read Iggy's plan and everyone's comments on cycling I could find and they talk about "seeding". Can I take a gallon of water from a goldfish pond and use that? What about putting a couple of goldfish in if I can't find pure ammonia? If I find the ammonia, it still isn't clear to me if after I get the reading up to 5ppm is the goal to keep it at 5ppm until the nitrates come up or am I suppose to keep adding the same amount of ammonia every day that it took to get it 5ppm? It would seem to me that could get it even higher at first. (I have a 16 gallon tank)
