Lingtime,
Not sure why the frustration

. We are all here as fellow hobbiest to share info with one another. I tend to read a respond to most posts where I fal I can contribute. Others do this as well - personal opinion is it is better to refrain from a response when I have limmited experiance on a specific issue.
That said I looked at the prior posts and Judge answered your initial post with several querstions in less than an hour after you made it. I hope you agree with my sense that is very good responsiveness

. You made a post that was a bit confused saying the edit works and no new data so there was nothing to work with really.
On this particular topic I am not sure what you are seeign. The ones at the pet store are probably coraline alge which is a good thing to have. I have never seen that in a white color so I have no real idea what you are seeing. Can you post a picture, a better histroy of the tank including current water parameters
