Temperature
 

My tank isnt looking to good(frog spawn isnt opening and my feather duster isnt extending to its fullest. I tested the water and the only thing off is the temperature.

Any suggestions would be great.

What is the temp?

Temperature is very important! I was not home one hot summer day and I tank went up to 85 :mad: I very fortunate that I only lost my colony of ice fire enchinata.

my tank spiked up to 90 and i lost all my corals fish were fine.

83 is the temp..

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.

Magnitude of temperature is less of a problem (unless you hit something like maybe 90) than the spike like Kien said. Even a tank can get whipped out if you temperature sits at 78 but you had a spike in a hour and BAM! I have kept my old tank between 81 to 83 so the temperature is not as issue. Probably you had a spike?

When something doesn't look good and I can't find any reason for that, I do WC :)

If your tank is hot and you have no means of cooling on it put a fan on it get the air moving around my house is currently at 37c and all my tank has on it is a small fan and the water in my 33 gallon is at 28c fans do a great job of cooling tanks in a cheap way

If you have cooling then as others suggested look elsewhere
