I have an Ink Bird WiFi heater controller along with the BRS 100W Titanium Heater Element. I measure the temperature with the RedSea ReefATO+ and I can see that it fluctuates significantly during the course of each day and will often exceed the max temp the heater is set to. I’m not talking about the sharp spikes, which were caused by turning the pump off for acclimation, water changes, etc. I’m talking about the long, consistent increases and then decreases. I could understand if it was happening every day and could be explained by heat from the lights, but these big swings aren’t happening every day.
Any ideas why this is happening?
