Just out of curiosity but has anyone experienced cloudy water when dosing Seachem Fluorish Iron or Seachem Fluorish? My water is fairly hard and Ive heard that the Iron may be reacting with my hard water to precipitate out of solution? I read that Erik Leung doses at night to avoid this water cloudiness and Ive tried that except that the cloudiness stays until the next day. My gH is about 15-20 degrees and kH is 6 degrees. Sorry to get off topic here. My 2 cents is that fluorish is a very good trace source although I will be trying out Plantex CSM+B very soon.
