I know you are going crazy! I was there two years ago when I had a intex pool. You didn't mention if yours has the skimmer that hangs on the side. If it does, I would use a filter sock if you aren't already. Those intex pumps just take forever to clear the water. The pump never gave us any trouble as long as I was on top of my water. But once I got algae is was almost impossible to get it clear. Keep the pump on and clean or change the filter as often as you possibly can.
