Can anyone lead me in the right direction for a hydrometer that i can put in the tank and will alert me when temp is too low or high? Waco seems to be doing well except for the recent poo surrounded by water. Went have a fecal tested this week and they didn’t see any parasites . But after googling for 24hrs i am now putting a repti sun inside tank and che bulb on top of screen and concerned about the humidity getting to low on the basking side since i installed the digital hydrometers.
