I live in pnw and we are having a crazy heat wave. My 65 gallon freshwater tank usually stands at 78 degrees and is currently at 83.5 my Congo’s are not acting right, my roseline sharks have lost their red color and the shrimp are moving slow. I am afraid to add cool water because I don’t want to shock them more. What is the best thing to do?? It will be 107 here tomorrow 10 degrees hotter than today. I’m so upset and need your help!! Save my fish.
