I think I have Dino, just not sure on the type. First time using a microscope so hopefully these are ok photos. If it is dino what is the best way to fight it. Phosphate was tested yesterday at .02, Nitrate 0. Thanks

Here are a couple of pics of some of the rock, it is kind of a cream/tan color, super slimy. Attaches to everything, glass, sand, power heads ects.

Anybody have any ideas or how to get a good sample to test under microscope?

I think what is throwing off your microscope pics, is that there are multiple species at play and different sizes making focusing difficult. You could take a sample and kill whatever is in it with a few drops of rubbing alcohol, when they are not moving easier to focus on one individual specimen.
