Hi Alexander
You asked so I will try to provide an answer.
Several of us have tried to kindly explain to you what the community considers an Emergency. I even attempted a bit of chicken nugget humor

. When you bristled instead of saying "Ahh thanks, I get it", it kind of unfortunately invited a dogpile.
Revhtree is the owner of the forum and he also explained what would typically qualify, both to clear the dogpile and to help you understand. There is not an exhaustive list of what constitutes an "emergency". It is simple spirit and intent kind of thing. Like the attempted chicken nugget 911 humor. Yes, to the person with $5.00 to their name and starving, getting shorted a nugget is an "emergency" but not one for 911. Same logic here...
Rev is not only the owner, but he is one of the nicest people you will ever meet. Instead of locking this thread, he simply attempted to clarify how "emergency" works and also asked people to calm down. A chance to reset with a kind response. So, instead of lashing out at people who he already openly asked to back off - how about we just reset and get back to understanding what is going on in your tank?
