I have notice alot of high flucts in temperature on my 92 gallon corner tank... i dont have the heater on anymore due to summer time.. but sometimes like today i noticed the temp shoot up to 87.3 to me thats hot... but at night it will drop.. i know its a normal fluctuation in temp.. but will it hurt fish? I only have a few angel fish and discus.. along with my FRT... so during the day its 87 ish and at night drops to 80ish... i dont want to waste money on a chiller... any ideas? i have had no problems just wondering what other people do?????? thanks
