Just got a brand spanking new aqueon present heater yesterday shipped from Amazon. It is supposed to heat to 78°. I followed the instructions by letting it sit in the 20 gal for 30 mins before plugging in. The red light sometimes turns on for like 10 seconds but the heater does not heat. The tank is at 64° and my fish are at risk right now. Anyone know what to do?
