Im treating my tank for ich w/ salt and higher temps (82-84). Right now my tank is in front of the window. Normaly this is cool because I live in the woods, but when the leaves are gone in the winter the sun hits the back of my background and raises the temp. My question is during the day my temp is around 84-85. At night the temp drops to around 79-81. Is this going to hurt my fish? Before everyone stones me about the tank infront of the window I know I should move it and will asap, but for now is the temp flux cool? :joke:
