help with adjusting please

[mbar]

I was away for a couple of days, and I was just wondering how is the pool doing? Waterbear is right, the sequestering agent will lower the ph a little, and I would think that you have enough in there now - so is there still a lot of stuff fall to the bottom of the pool? If not you can stop vacuuming to waste - You also may want to try to turn the filter off every night to see if more settles out. Let me know how you are doing

it has cleared alot now. still some falling to the bottom too. i am going to vacuum more tonight, but i will on filter now.
you can see all the brown stains. i did try a vitamin c tablet and the stains will rub off. i need your advise now on how to try to get rid of the stains.
thanks for all your help!!
