Hi All - I'm doing a fishless cycle of a new 15G Waterbox. This is my first tank in this reef hobby. Question: do the water temperature spike during the bacteria and ammonia cycling process? I dosed it with IO Bacterial and Dr. Tim's ammonia last night and ammonia got to 2ppm. Tested ammonia today and things looked like it is going to plan with ammonia dropping to 0, and nitrite now at 5ppm. My question is why did the water temperature remained high? My ambient room temperature is 79 but the water is 83.3 without the hood, and it was like 84.2 with the hood on. At first, I thought the new heater was "bad", so I unplugged it for the entire day and the water stood at 83.3 after i removed the hood. Is it because the bacteria is working overdrive and causing the heat? Wondering if anyone came across this issue. I tried Googling for an answer but didn't get a clear answer so I hope the R2R community knows right off the bat, we have the smartest reefers on the planet on this forum - right? Best Regards.
