Water Temp. Question
Hello. I just had a question about the water temperature in my new aquarium. We just setup a 75 gallon tank a few days ago and are just started cycling the tank. The tank is not in a spot where it recieves direct sunlight. I have a digital thermometer with the sensor about halfway down and on the end of the aquarium. The heater is approximately in the middle of the aquarium-. It is a 300w (i think) Rena submersable heater.
I've noticed the temperature fluctuates throughout the day slightly. It's just in tenths of a degree and usually ranges from 75.9 to 76.5. My question is...Is this too much of a tempereature change to be happening daily? Should I think about getting another heater? I've seen a lot of people suggest having two heaters anyway, but will having two stablize the temperature more? The aquarium is going to be a freshwater community aquarium.
