I have an Intex 16 ft round ultra frame pool. The pool has one suction and one return. The pool has a skimmer that attaches by hanging it over the side of the pool and using a hose to connect it to the suction. I don't currently have this connected as I am trying to clear the pool and the skimmer had algae so I've washed it and set it aside.
How can I add DE to my sand filter if I don't have a skimmer? By opening up the filter (removing the valve and unscrewing the clamp) and pouring it on top of the sand?
