I'm assuming that you have a sand filter. If so, you can do like many of us with sand filters do and that is to add a little DE to your skimmer. It will help to filter out the tiny stuff that sometimes sand can't catch. Add only enough to make your filter pressure go up by about 1-2 psi. Add a little to your skimmer and then watch the pressure. It may take about a half hour for the pressure to rise. If you add too much, it may clog the filter and then you'll have to backwash it out. My pool is almost the same size as yours - 24 ft AG with 48" walls. I added a half a cup yesterday and it increased my filter pressure by about 2.5. So, in your pool it would probably increase it by about 2. If you want, start with 1/4 cup and see what that does for you. This may help clear it up for you.
