Hi all, I have a paludarium with a bunch of plants/orchids. The tank has very good air circulation with 2 pc fans (18 cfms each, so 36 cfm air movement in a 29 gallon tank). There is no mold anywhere in the tank except one small area...it's weird that this one spot has it but nowhere else, and I haven't had a mold problem in months. Anyway, the mold is a very fine fuzzy texture, sort of grayish in color, and is creeping over some moss...unfortunately it's very close to my Bulbo. minutulum and Bulbo. catenarium which are tiny, rare species. There are no animals in the tank, but if possible I'd still like to use a non-toxic treatment for the mold...also I am hoping I can use something that will not kill the live moss and liverworts I have all around the plants. Any suggestions? Thanks!
