Well one thing you may want to do is put it right next to the filter. So the heat is put everywhere. Also it will feel cool, it usually always does in the summer. When i had my discus tank, 84*f. It would feel cold sometimes. It is just how the skin works.

Also what thermometer is it?

I have never used it before. So it doesnt touch the water?

But usually the regular glass thermometers are the best.
