My Heater is set to around 78 degrees and stays around this temperature during the evenings. I have the Finnex planted + 247 lighting on the 247 setting. I live in Houston so it's pretty hot but I set my AC so that the temperature gets to a maximum of 75-76 during the day. However every time I come home from work the tank is often up to around 80 degrees. Is this a big issue and are there any suggestions? I'd rather have the temp around 78.
