I don't believe anything you show because you have a bad reputation. For one, I doubt you have the expensive equipment needed to film protozoans in action. Two, knowing how deceptive you are I don't doubt that you just applied a drop of chlorox to the specimen slide which would cause them to disperse and then dissolve. And your pond water test shows nothing more than your killing algae (which is a single celled plant, not an infecting microbe). And to do that you probably just added chlorox to the water.
