I had to cut back the foggers because it (Aided) in killing off half my plants and creatures. (The novelty has worn off)
For three months I used it for 1 hour at sunrise/sunset with conditioned water and with natural spring water (Not from a bottle, from an actual spring)
The conditioned tap water had horrible effects... rotted most of my plants, added a nasty mildew/bathroom smell and forced all my frogs to high ground while the tank was being fogged. (They also shed every three days when I used the fogger, I thought that was normal until I stopped. Now they shed once every few weeks.)
The spring water caused black surface alge and accelerated a bacterial growth that made my tank sulferize. (Super fast decompositon aided by an outbreak of microorganisms, turned my nice terrarium into a bog swamp. (Killed five rough skinned newts (Spoon nose) and killed two california rough skinned newts, accelerated mouthrot.)
Not a pritty sight!
Also, I ended up getting sick due to the excess "Stuff" in the air... like a mini pnemonia... Nasty flemming, hacking cough, shortness of breath, and a cold clammy feeling. (Though my room humidity stayed constant 50H, my tank was a steady 80H)
Now, my room is still 50H and my tank stays 80H without the fogger... I saw no added bennifit of using this again, and it DIDN'T raise the humidity, only the moisture level. (The drops condense too fast to actually add humidity (Possibly in a closed system or a bare tank). If you see any humidity it is because you had no moisture level in your tank at all, and now you added moisture.)
I had to scrap my soil, scrap most of my decorations, scrapped my stones... Scrubbed my tank with WIPE-OUT 1 to kill any bacteria and fungus, and then reconstructed my tank.
(Once again, my final verdict... Foggers are a novelty, and not worth the effort. They do more harm than good, but make a neat display if you want to add cool visual effects, once in a while, when guests come over.)
(There are reasons that I am opinionated, because I use this stuff (as directed and as not directed), then determine my opinion of the products or setups. Feel free to disagree.)
The best moisture additive is still live sphagnum moss... Yes, you can find it locally on almost any ground... or purchase it from plant stores. Dead sphagnum = dead animals... They breed bacteria and fungus and MUST be changed weekly, they also have the potential to grow a bacteria that is lethal to humans, unless boiled. (Sponges are similar, but not lethal to humans.)
