ok so i have a 30 gallon and i have the heater for the 30 gallon tank. the temperature of the water should be 76-80. I set the heater to 80, but the temp is still about 70 and sometimes drops. i'm scared that my fish might die due to stress in the constant temperature drop. someone help.
i've raised the temperature pass 80, but it didn't help.
