at a lower kh ammonia looses an ion turning it into the chemical compound ammonium which is a lot safer for fish with regards to toxicity, adding raw ammonia to a tank is madness, if ammonia levels are to high to begin with then ammonia will damage the bacteria that feed on it, i am all for finding a way to cycle a tank without risking fish health but adding raw ammonia, unless precisely and accurately measured is going to cause problems, using small amounts of fish food is much better, but for gods sake dont put raw ammonia into a fish tank!
the only way this would work is if someone out there has very reliable dosing instructions, and if you slip up then your gunna have to start again....and again...and again....

5-6PPM of ammonia is NOT going to harm the bacteria in any way. In fact, it's like giving it a feast.

it's not really that expensive, because you're only using one at a time.

yeah, the bacteria is growing in the filter, not the water. and then at the end you'll have lots of nitrate, which will kill your fish. that is why you do the large water change.
