i wouldn't worry to much, my temp probe failed once(always happens when i'm away for a weekend) and my chiller ran non stop, i came home and found my tank at 68 degrees, most corals were stressed but after a few days they recovered.
I have been checking my water like crazy I couldnt even sleep last night. Im all upset over this. It took me so long to get the tank the way I wanted it and now it looks like its all over.
My ammonia seems to be a little high.
My phosphates are at 0.5
Nitrates are at 20
nitrites are at 0
ph is at 7.8
I have a 29 gallon bio cube and I did about a 7 gallon water change.
