Hi Danel. I would love to read the article about this. I am sure cloudy water can happen in healthy water, but I don't think you can automatically rule out unhealthy water if you have cloudiness.I have come away from this idea now, after doing some heafty research, I have found that the cloudy water is in fact a sign tha my paramaters are healthy as this sort of bloom can not happen on an unhealthy tank, so I will just continue with increased water changes and gravel vacs and just wait it out one day at a time
