Water temp

[spdjnky]

The water temp is 2 degrees higher on the far side of my aquarium. I just noticed when I was checking my onee temp gage that was reading 83.9 and the other side is 81.9. I was thinking I need another power head on the other side? I have a fan blowing on the sump. And I live in upstate NY it's a hot summer.
Welcome any one input thx Phil

Your temperature gauges (thermometers) are off and need to calibrated with a trusted thermometer, the water is not off by two degrees.
