Calced all my stuff yesterday, and only one thermometer was correct, and it's my floater which takes 3 weeks to get a temp. Bought one digital that had to be sent back because it wouldnt calibrate, and my metal therm was off 3 degrees. Hydrometer read 1.003 at 60f in tapwater. Not surprising considering they came in my original kit, and none of that was really quality stuff.
Anyway, can anyone recommend some quality stuff?
