wats a good organic ph down? can you use apple cider vinegar,it kills funguses,will it hurt the good bacteria? peace barney/
The two things I know are sulfur and lime.. Sulfur lowers and lime raises Now I haven't used it but I read that people can use vinegar and the real Organic kind is loaded with things the store shelf kind doesn't have. There was a thread with the info here. Try a search for vinegar or organic vinegar.
