Quick update after Zhng my chiller After zhng my chiller with external probe, only on for 1 hr and off 2hrs. Meaning every 3 hr only on 1 time which is a big difference compared to using original hailea probe. See the seneye tracking data, black arrow represents point of change to external probe. Before that, tank temperature is very stable but its like on once every 20mins zzz. After change the temperature fluactuate slightly more but its only like 1 deg +/- so dont think is harmful, shall monitor for longer to see if that translate to electricity savings. Jialat give them anemone dun wan to host now disturb my torch. 人算不如天算. Thanks for reading! Covid cases coming up, stay safe and happy reefing everyone! Sent from Singapore Reef Club mobile app
