What are some of you folks using for your sources of water? I am curious as I use a Pur filter to bring my pH down from 9.3ish to 7.5ish and to help filter a small amount of contaminates. I like this because it is a simpler form of RO without leaving dead water behind. My only problem with this method is it takes A LONG TIME to filter the water, especially with larger number of plants. It's starting to become a hassle and I am looking for quicker ways of getting my water cleaned.
