Hey everyone, need a bit of help on this humidity problem. The set up is a 20 gallon aquarium, rocks as substrate sitting in water, two neps in the center, sealed at the top, fan set up, humidifier, and tank heater at the bottom. First week or two were awesome with constant 99% humidity and 82F no problem with only having the humidifier and fan going off every two hours and hardly any condensation on glass. Now it struggles to reach 97% humidity, and slowly drops over the two hour gap to 90%, temp stays constant at 82F, and now I get a lot of condensation. Only thing I can think of is that its heating up because of spring, AC is going off more, cooling the room, Temp difference of about 10F between room and tank is pulling humidity from the tank and condensing it all on the glass. Besides that I have no clue.
