We have left the house before and turned the air off with no problem. However, this time around we didnt expect it too hit 119 when we were gone. Sadly, the fish were long gone, and the water was full of miscellaneous fish parts. I immediately took out the fish and drained all the water several times. I have a test kit. How do I know when its ok to put fish back into the tank? Specifically, what should I be looking out for in my tests? Thanks, its off to aquabid to fetch me some more fish...
