Temp reading

[seadoggy]

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.?

In my experience, those self sticking strips are very inaccurate. My 46 gallon bow had one on it when I converted it to a SW tank and it was way off from a glass thermometer. My glass thermometer is reading the same as my chiller controller.
PEEL IT OFF AND TOSS IT!!
