I was just scanning the threads and thought I would make a comment on this one. I live in a very rural area and the one grocery store where I live has started selling Wardley's Safe 2 O complete water conditioner. Eliminates Chlorine and Chloramines, Neutralizes Ammonia, and Stabilizes PH to 7..All of their claims are true. I have been using it for about a month now and I have started noticing white flake buildup on the tank glass and around the heater. The white flake buildup just peels off easily with a light scrubbing using the algae scrubber. Just wanted to let anyone know what to expect if they decided to try this product. Since I live in a rural area, I will use this if I have nothing else...But, to me anyway..Prime Water Conditioner is the end all to looking for anything else to use. I really like the Seachem Products and I have used many of their products over the years.
