Well, I just re-did my viv and mold is beginning to grow under the soil. I was not to concerned about it at first because it was satying in the soil and not spreading. Well now it is beginning to spread on the surface now. I sprayed one area with Methylane blue and then covered it up with fresh soil so the frogs cannot come into contact with it. But now the mold just seems to pop up in another area. Does any one have any recomendations on how to stop the mold growth? Also something wierd is it only grows where my fan blows in fresh air. Very strange.
