Set up the ATK today. I think i have a siphon from the topoff container to the sump. The pump kicks on at the lower sensor, and I think it's shutting off when it's supposed to, but a while later the alarm on the FMM module trips and I noticed that the water level in the sump ends up being too high. Not sure how to fix it except to run a solenoid in series with the pump. Any thoughts?
