I have noticed that for a few months now my plants seem to getting black spots on them and changing to a yellow / black and many new leaves falling off I was wondering if there was anyway of saving them . Tank details: Ph 6.8 nitrates 25 nitrites 0 Gh= very hard . Water temperature 23.5°c /74.3°f 15 gallon tank . The ammonia is low but I think it might have something to do with the ph and how acidic it is because my water hyacinths leaves are disolving .
