I just switched from a heat lamp to an under tank heater with a thermostat. My humidity was steady between 50 and 60 percent, sometimes below at 40 and i would mist it a bit to raise it back up. But now that I am not using the lamp anymore the humidity is at 75 - 85% I guess because its very humid in NJ this time of year. Is that too high? What do i do if the humidity levels go too high to bring them back down?
