I've never dealt with foggers or misters, or managing humidity. But all my frogs seem very happy, they're very vocal. I'm confused with how lowering the wattage of my light and adding a heating pad would help humidity. Either way the temp will be rising to 85 deg. ...so heat rising = humidity lowering. (Side note- the greens escape higher temps by sitting lower in the tank when stressed, the higher temp is present only within the first 5-6 inches of the canopy.) So, if I'm lowering the wattage of the bulb..to reduce the "intensity"... of the heat...yet adding a heating pad....to increase ..heat... thus raising humidity? that doesn't sound right or maybe I'm not understanding the process. As for the water chlorination, its a simple enough fix. I honestly hadn't thought about it since I didn't see any mineral build up on the glass.
