I have the probe to my dbs-1000 placed directly on the heat tape and have it set at 90, the thermometer i have inside of one of my tanks says hot is 85 and cool side is 75, should i place the probe inside of the tank? Also, i just set up my night drop (i know, im starting late), I have a few questions, does the dbs let it drop to room temp until the morning, and then bring it back up to the set temp during the day, or does it regulate the temp at night also? Thanks in advance.
