So my heater does not work too well and my tank temp goes from about 73-74 to 78-79 every couple days. Is this ok? Or what are the " side effects" from it? Thanks
The temperature in my smaller tanks fluctuate four degrees per day, on average. When the lights are at "full throttle" the temperature can reach 80 degrees. Yet, in the mornings before the lights come on they're at 76. I do not believe my fish are affected by that swing.
Try splitting the watts between two heaters and place them at opposite ends of the tank. See if that helps.
