ok ive had my brinsea eco 20 up and running fr a few hours..temp is spot on but humidity is driving me looney! checked it 2 hours ago, it was at 55% so i added a touch more water (only half filled one reservoir and left the other empty) i checked half hour ago and humidity was at 35%????? stuck a different hygrometer in and it gives the same reading, so ive filled up that one reservoir to the top and its only up to 40% humidity should i fill up both then or im never gonna reach 58%! then what do i do when i need the humidity higher at hatching time? if i alredy have both channels full theres no room for more water?? vent is open half way.
