Excuse me Rb- did I misquote you? Did I fail to quote 100% of what you wrote? I did not. I used your exact words and none were put in your mouth except by you. And when you say
I never claimed "0" was the target, I stated zero was reasonable as opposed to .25-.5 ppm on a fishy cycle.
How can you possibly think that doesn't mean that 0 is where you want folks to be. Stop playing semantics, you are clearly arguing for 0.
On the other hand you did misquote me. I never said I was not in chat, I said over the past year I was almost never there. And that is the truth. I tend not to go in when certain folks are there. And exactly how long was I in chat, and don't count the long idle time where I never said a word because I was not participating and had simply forgotten to log out. I don't go into the chat much any more as it long ago stopped being a fish chat but had morphed in almost 100% social chit chat.
And finally, I have shown you to be wrong about most of what you have said in this exchange. And your only response is to claim you never said what you said or that I misquoted you, which is also a misstatement on your part. Why have you failed to respond to a single point I have made not just using my opinion but backed up by statements and research done by folks far more qualified on these matters than you or I.
But lets make it real simple Rb. I have stated unequivocally that a reading of .25 or even .5 ppm of total ammonia is only a concern if the ph and temp are at or above specific levels when considered for a short term period, i.e. the 10-14 days that it should take a properly done fish-in or fishless cycle to have ammonia reading 0.
So you can keep on insulting me personally rather than admitting you have your facts wrong, I no longer care. Your erroneous opinions do not change the science involved any more than your saying the earth is flat would make it so. I strongly suggest you do some research regarding the toxocity of both ammonia and nitrite so you will actually have some basic in fact for what you say. I will even help you out in educating yourself by offering the following lab studies on the topic. Maybe this time you will actually read some of it before you respond?

If you want more got to Google Scholar and Type in "ammonia toxicity for tropical fish" or "nitrite toxicity for tropical fish" or "ammonia and fish". Any and all of these will get you lots of research studies.
