Temperature

[kien]

What are your other parameters? What is your maintenance schedule? What is your temperature normally at? I would only consider 83 alarmingly high if your temp averages something much lower like 75-78. A lot of people will keep their tanks higher (79-82) so for them 83 wouldn't be an issue. So if your tank is not used to the higher temps and you get a temp spike then yes, it could be an issue.
