I have two coralife thermometer one in the sump and one in the DT plus the thermometer from the reefkeeper in the sump and the one on the chiller so I have 4 different readings and am just trying to get one main temperature from the DT am getting 81.2 and sump 79.3 those are from the coralife and the reefkeeper in the sump its at 75.7 and chiller is 74.6. So what's a good thermometer that can trust out there because am just getting all random temperatures
