Hey there hope this is the right spot to post! I have had my redfoot for 10 months now and we have gone through some highs and lows of temperature! I currently have a set up I like with the CHE on the warm end over a water area at 92 and the cool side being 85 usually. The humidity levels are hard to keep up though and when I use a tank humidifier the temperatures drop 10 degrees! Would using a CHE of 100 W in my 4 foot tank instead of a 50 W be safe for the little guy and make it so the humidifier works out? Any advice would be greatly appreciated by us!
