Bests & Worsts Reviews from Amazon

I have a filtration system consisting of an air injection filter, a salt brine softener, spun cotton, gac carbon, and cto carbon filters. I have all this because I have high iron content in my well. It was obvoius from the brown staining in my showers and toilets. This parameter alone (iron - third down on the chart) should show tremendously different between the "well" to "injection, softener, cotton etc..." image. It doesn't change a bit. After seeing this, I decided to broaden the tests. I tested after the air injection filter only. SAME. I tested my pond water. SAME. I tested rain water sitting in my boat. SAME. Same across all parameters across all samples... Each sample was submerged for 2 seconds, held horizontally while shaking off excess water, and the image was taken 30 seconds after submersion. Not a single bit of difference. A picture says a thousand words, see for yourself and save your money. By the way, I didn't even bother with the bacteria tests as they have conflicting color indicators on the bottle vs the paper instructions vs the description here.
