Amquel: am confused...
I've been thinking (probably a bad sign) about Amquel and cycling, since I was reading a post in the NTTH forum where someone was concerned about die-off on live rock during the cycle. I mentioned water changes, but was wondering about Amquel.
In this thread, you talk about not dosing Amquel through the cycle, but the thread made me wonder about the tradeoffs or problems involved in it. I didn't see a thread in which you got more specific about the issue, but maybe I'm not so good at searching...
So what issues might there be? Or are they even known? I understand the risks of not developing a bacterial population, but if a tank is showing 4ppm ammonia, isn't that a bit more than is really needed?
Some people have asked about using Amquel or the like as a replacement for cycling, and I've counseled against it, but I don't really have my rationale or references ready.

It was my understanding that Amquel and similar products somehow "fixed" the ammonia and kept it from being toxic to critters. In the "fixed" state the bacteria were supposed to still be able to digest it. Thus the bacteria population would still thrive, but larger critters wouldn't suffer.

It might well help in the way that Chris suggests.
It might also drive the growth of different species of bacteria, and not allow as rapid build up of bacteria that actually use ammonia.
I really don't know what effects it will have. To some extent I expect the answer depends on how much you add, and for how long.
