Was in bed lol but got up and went and turned flow all way down and seems to be keeping it level. Tomorrow ill get to figure out the sensor for ato since my reservoir is coming.maybe since you’re running too much filtration on chamber 1 and 2 that it’s starving the last chamber. try adjusting that . i’m only using a filter cup from TheKrakenReef with floss and the bag of carbon on chamber 2
