Your really not getting it this is a quality lab grade old school type German made top of the line not an off the shelf cheapo
I'm not naming name cuz this is probly a 1 in a 1000 error and I won't hold it against them
I'm just warning everyone to triple check all equipment with other equipment to verify accuracy before use even if it is the best of the best
Iv been running high since the start of the tank and just a few degrees warmer was really bad
It's now sitting at 82 night 84 day was a constant until it moved a few degrees to 92 not the 82 peak I thought it was at
