What to do about particles floating in pool

pool

We just bought a home with a pool. I've done a bit of research online, and feel pretty comfortable with the system, but one thing is bugging me. Regardless of how long I leave our pump on (sometimes for 24 hours or more), when I look at the water, I see tiny debris throughout the surface of the pool.

I've tried using a pool net to scrape the top of the pool (several times) but the particles never really go completely away. Our pool is in a screen-enclosed area, so I don't think it's anything external.

We run a pool vac, which gets the bottom pretty clean, but I just can't seem to get rid of the smaller stuff floating on top. My next move I guess will be to recharge the DE filtration system… but I wanted to see if there are other causes for this that I could remedy before dropping $150 on a tech to come out and clean/recharge the filter?

Is the skimmer basket unit working properly so that the pump sucks in water from right at the water surface? If not then repair or replace it with new parts as necessary.

Your DE filtration system may have some problems. The internal screens that hold the DE matrix in place may have holes that allow water to go right through the filter without passing through a layer of the DE material. If so then the problem screens would need replacement.

It is also possible that the last time the filter system was replenished with DE material that not enough was added and so some portion of the filter screens are not covered with a layer DE material or the layer is way way to thin. In this case your planned back flush and maintenance check of the filter is in order.
