I was having problems with fine dirt settling on the floor of my pool. I only had the venturi style vacuum to use and all it did was blow the dirt straight through the bag and back into the water. I found an easy hack to help eliminate that problem. You will need a/c pool filter ( for my vac head the only one with a big enough hole was bestways brand), an old, large tube sock and a piece of plastic to cover the hole on the far end of the filter.
