ok I have the vacuum head and long pole with hose but I dont understand what you mean for me to do that is different from the way I currently vacuum to waste.? Im sorry, Im kinda "blonde".

What is polyquat? I have a bottle of something called cloudy water clarifier that says it combines small particles for easier filtering. Is that it?

======================================

you know what, I think I understand........."vacumming" the way you suggested would have a more gentle pull on the debris than it does with it hooked to the pump?. Therefore less disturbance to the debris, less a chance it will "puff into oblivion" before I suck it out?
