Ok so I saw a post on this a few weeks ago, but can not seem to find it. I am having some mold issues in my terrarium. mostly on wood. I think I remember seeing in the post to use a vinegar water solution and spray it on the wood!? I also have some small patches like one or two, on the substrate. One of the post said that the mold on the substrate will cycle through. I think I may of seen some thing about distilled water also to get rid of mold. The wood piece that it is on can not be removed. So will the vinegar solution harm the frogs at all? And what are the proper steps to getting rid of the mold? I do not have springtails yet but will be getting some soon. Also I am just a little slow in the head, what is distilled water? lol.
