I have been having issues with not being able to clear my cloudy pool. I have gone to the pool store and had my water tested several times and each time they tell me to do something different. While now I have a pool where I can see the bottom but still a bit cloudy and on the greener side. I noticed yesterday as I was vacuuming (I had the setting on filter rather than waste) that the dirt was coming right back into the pool. I am thinking this is why the pool is not getting any clearer. If so, what do I need to do to the filter, change the sand? I sometimes vacuum on waste and sometimes on filter, I have well water and it takes a long time to fill back up, which is when I filter. I backwash every time I vacuum, even several times during the process. I am not sure what my filter is other than a Hayward 1 hp.
