I just bought some Provent a Mite for my BP which came in with a few mites. I've never used it before and it says not to directly spray it on the tank, but on the substrate. But my substrate is just paper towels, so should I spray them or just go ahead and spray out the whole tank? It doesn't make sense to me why I can't spray the glass???? Anybody know or have any experience with the stuff?
Thanks in advance. I did a search on this but didn't come up with any specific threads on this particular warning on the label.
