Thermometers

[Myka]

I use $15 JBJ Digi-Temp thermometers and they all read the same as my AquaFX TDS meter (which has a thermometer on it too). My floaters read differently, as do the stick on ones. When I buy the JBJ ones I check all the ones on the rack, and you'll often see there is one or two reading a bit different...don't buy those ones.
