I've been using a temp reading strip that you apply to your tank, to measure your temp. Mine always reads 83-86. It does gets some sunlight during the day but not much. I put one on the top corner and bottom corner. So today I bought a sinking one and it says 80 degrees. What gives? I hope that correct because I can't buy a ciller for my 55gal.?
