Last week I picked up a few water test kits from the local hardware store. These tests are about $10 each, so the quality/resolution isn't great. They gave me a basic idea of how well the current filter arrangement is working. Each kit consists of a litmus-style "dip-stick" that you compare the colors to a chart. In most cases the colors were difficult to match exactly. The copper and iron tests were clearly 0 (zero) in all cases. These tests are without the eFilter I've been working on. The nitrate tests results were consistently abnormal (pic on the right). Both the pre/post filter results were the same for the nitrate tests.
