Mobius is currently bugged for Reefcrest anti sync where the child pump will sporadically drop to lowest speed or accelerate to the fastest. Suggestion from Ecotech: run the child pump off Mobius or run them separate. ETA for resolving via firmware or new Mobius update: “Unfortunately, I do not have a timeframe for the update, but my team will have it addressed in the next Mobius update.” See attached movie
