I have a very large water tank which is, despite the drought, completely full and, now there is to be a hosepipe ban, I will need to use this water. The water has been collecting since before Christmas. Can anybody tell me if this water is likely to be okay as it is for use on vegetables and fruit trees? Is it absolutely necessary that I apply treatments such as Biotal, which I would rather not do? Or is there a free to prepare and natural solution?
