sorry yes i ment the thermostat probe (black chunky thing ) , so i set it up today like this ,,,, digi thermometer probe on floor at hot end above the mat , i have put the matstat probe in the same place inside next to the digi thom probe , so both probs inside on floor above mat (hot end ) , the digital thermometer reading on the out display went to 90f then the heat light on matstat went out ,it went down to 86f then came back on again ,up to 90f ,down again etc etc ,
i read in ur reply u said put matstat prob on hottest part of heat mat outsaide tank is this wat i should do and what should my temp read as some people tell me 88f and some say 82f-90f ??? i am a little confused , thanks for spearing the time to listen to me dribble on ,, thanks
