Now that we are nearing Summer hear in Britain, the temperatures are starting to get constantly high. I have noticed that on my fish tank thermometer, it is off the top of the scale (above 86). I have checked my heater and the thermostat is set to 80, which is what the temp normaly is. I am assuming that it is the sun that is causing this excess heat, and is there anything I can do about it? My tank is never in direct sunlight, although my room usually is.
