The tank that has been identified as having Dinos, only through coffe filter test is next to a window with strong wooden blinds that have heat resistant paper film to help but the heat still travels somewhat. So, my tank with thermo-electric chiller struggled to keep 78-80F throughout the day, meaning the chiller never turned off. Now, that I have rasied the setting to 82F it turns off and takes breaks, my house has central AC at 78F. Hoping to make a dent with the dinos and not hurt the SPS in the process.
