I got a new Brinsea Octagon 20 Eco the other day, have turned it on to regulate it and for the life of me I can NOT get the humidity to regulate. Temp, is fine, used cold water, filled up 1 channel, left for 5 hours, couldnt get above 34%. Emptied water to add hot water half way up channel, it scooted up to like 72%, went to bed, got up its at 33% the past 2 mornings. I have read threat on top of thread, and keep seeing, ...Throw the book away. so book got put away and im still filling, emptying, filling. What am I cdoing wrong...me, I just want to hatch out half a dozen ducks!!
