    Dirt keeps returning

    I live beside a cotton field. Every time the farmer plows, my pool become the magnet for dirt. The next day, I can see the filth that is in the bottom. I go through the routine of vacuuming ( through the filter) and the next day the dirt seems to return, settling mainly in the seams. I've thought about vacuuming to waste and will to resolve the acute problem, but shouldn't my filter catch the dirt? Also, I only run the pool 12 hours a day, I thought maybe that's the issue, just not allowing it to clean. It's never been a problem in the past. I replaced my pressure gauge this year and it ran within spec for several weeks, now it reads about 2 psig vice 10 psig normal. Unfortunately, I can't remember if the gauge started reading low at the same time the dirt kept returning. Could filter channeling be the issue? Here are the specs on my pool

    Odds are nothing is wrong. When you vacuum, you can't help but stir up some dust, no matter how slowly you push. And the return also keeps things stirred up. And it settles out the next day.

    You can confirm the filter is catching stuff by attaching a sock over the returns. Remove it and turn it inside out after vacuuming. If it's full of dirt, something's wrong with the filter. If it's clean, its just normal dust.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
