    If you'll post a complete set of water levels using a drop-based kit, including Free chlorine, combined or total chlorine, pH, Alk, CYA, it will help us rule out some sort of algae, but the more logical explanation is pollen and everyday dirt that gets into the water and just settles to the bottom of the pool.

    How does your water look?

    Yes, I read the question correctly. You asked for an answer, and I gave you an educated guess with the information that I had about your pool.

    I know that it can gather so quickly because it does in my pool, as well as many others. When you vacuum the stuff up, chances are good that some of it dissolves into the water instead of escaping through the vacuum.....but if you don't have a sand filter, and aren't introducing sand, then chances are good that it's either airborne stuff settling out, or some sort of algae. If your CYA is 20, and you consistently keep your chlorine above 3, then it shouldn't be algae if your water is clear. Do you have any combined chlorine? Do you have overnight chlorine loss? If the answer to both questions is no, and you aren't introducing sand/dirt into the pool, then it's just everyday stuff settling out of the water. Vacuum it up, or stir it up into the water so that your filter can get it.

    I think dirt on the bottom of a pool is typical of everybody's pool. I can vacuum my pool one evening and by the next day, there is already a little dirt/dust on the bottom again. Of course, as soon as we are in the pool moving around, the dirt gets into the water suspension and you don't see it. Later, when the pool settles down after we are done swimming, it will resettle. Especially in the "tape lines" underneath my liner where the underneath foam padding is taped together. No matter how clean I seem to get it when I vacuum, the next day there is always a little on the pool floor. I have a feeling that is what is happening with your pool as well. BTW -- Welcome to the forum!

    i appreciate both of your answers but to me it seems its the same dirt im vacuuming up coming right back in the pool i was wondering if there is something wrong with my filter or maybe my pump is too strong for the filter and causing blow by with the smaller particles i thought someone might have had this similar problem.for there to be the same amount of dirt on the bottom a half hour after vacuuming it clean seems fishy thats all

    Your pump is overkill for such a small pool but I am not knowledgeable about your type of filter so I can't comment on whether it is a mismatch between the two or not. Maybe someone else is familiar with this type of filter and can comment on that.

    As mentioned; your pump is way over sized for your application. If it is 220 volt, look for a dual speed motor that runs at 1 horse and 1/6th horse. You should never use the high setting. Be sure you get the correct "Frame" for your application. If your pump is 120 volt, look for a third horse motor or smaller or figure out a way to run 220 out to the pool.

    I did not recall seeing if you cleaned the cartridge after a vacuum to see how much of your particulate matter was picked up. With that, as with a sand filter, too much flow could blow debris right back into the pool.

    Could the pump be blowing by the filter? Heck, that pump could be blowing your filter to shreds.

    And finally, your cartridge may have holes that are not obvious unless there is a close inspection.

    As for the overnight dust; very viable and very common no matter where one lives. My pool is in the woods in Central NC and my brother has the same inground pool setup in Whitehall, PA. I actually have much less dirt on the bottom than he but more plant debris and bugs. One benefit I have with my dual speed is that I run it 24/7 all year round on low and only use high to backwash or vacuum to a 200 pound sand filter. The only problem I have seen with this method is a new seal every three years which is a piece of cake to change with my Hayward Super Pump. Well that and no open/close seasons for me either.

    Good luck and let us know how you fare with this.
