I changed over all of my tanks to tile and i have under tanks heaters on all of them. I just want to know what setting everyone using this setup has their Rheostat set to? I have it set between Low and Medium and the tile feels warm but i'm not sure its warm enough (i had it at medium but it felt maybe to warm). Is it Ok to put one of the temperature sticky strips on the tile, will that give me an accurate reading? (if yes what temp should it read?) I have only one digital thermometer with a long wire to the sensor that sticks to stuff and i'm using that in my crested tank. I can't find anymore like it either, i've looked everywhere.
Thanks in advance for the input
