You want the chlorine to keep the water germ free so to speak. It will cause organic matter to settle out of the water but that uses up the chlorine so to speak. The filter will catch a lot of this stuff and allow the chlorine to do its job.
One thing you are fighting with a pool is that it acts like a clarifier. If you have been to a water or wastewater treatment plant they have clarifiers. This is usually round and just slows the water down and allows solids to settle out, just like a pool. That is why an intake on the bottom of a pool helps so much, to pull anything settling out into the filter. It is also the reason you need vacuum a pool, to catch the stuff on the bottom. No filter and this stuff just keeps recirculating.
That's why a pool that gets used frequently is cleaner than a pool that gets used occasionally.... the people stir up the water and the filter catches the stuff, VS a pool that just sits (even with the filter running), stuff settles to the bottom.
Even when we don't use the pool, it has to get brushed and vacuumed weekly or you can see stuff settling on the bottom. It forms in places where eddy currents slow, or in depressions on the bottom, like if your sand bottom wasn't level or got footprints when the liner was installed.
