I went through the shock process (thanks to this forum and all the people helping!) and the results were very good. reached less than 1ppm drop over night and went from cloudy to clear. The TF test kits shows everything right in line now.
The question I have is how clear can I expect my water to be? In the daylight it looks pretty good but at night with the light shining through it i still notice a slight haze. Is this a limitation of my cartridge filter? It does run a lot, 6-8 hrs per day for a 7000g AGP with very little use. Anyone have any pictures of their water at night by their light?
