I recently bought a house with an IG vinyl lined pool. This is my first year maintaining the pool. This may be a silly question, but I am having trouble getting my pool clean (it's clean, maybe I should say sparkling). We have had quite a bit of silt, pollen, leaves, etc. in the pool this spring, and we vacuum about once a week. However, everytime I get done vacuuming some of the silt seems to return the very next day. Is this silt that just gets suspended during the vacuuming process (stirred up) and then settles back down the following day? Is that typical? I try to be careful and go slow, but sometimes I have to scrub to get the silt up.

My other thought was that I am actually vacuuming up the silt, but it is just not getting filtered out and then ends up back in my pool.
