Can someone please advise me on the best way to maintain the proper level of humidity & temperature in my RT aquarium? I'm having a difficult time keeping the humidity at the ideal of 80-90%. I currently use eco-earth subtrate which is coconut coir but am still constantly having to mist the aquarium because humidity drops to 40-50%. I have a 40 gal glass aquarium & have placed a 150W powersun bulb on one side of aquarium but for some reason, temperature remains on average 80-85 degrees. Based on my research, this is not the ideal basking temperature. Any advice will be greatly appreciated!
