Filled intex 16'x32'x52" pool with creek water,14,500 gallons. In Eastern ky, couldn't have it brought in and to far away for city water. Have a well,but couldn't use it to fill pool. Of course after getting water in, shocked before bed, brown the next morning. Took to pool "PRO", he said he could sell me a lot of chemicals but just to add 10lbs of iron out and it will clear up immediately. So we added it, and in 5 minutes it was pretty Caribbean Blue water, with a little cloudy to it, couldn't believe it. Had to fix chlorine level and ph level, but after 2 days all readings were perfect, but still cloudy. Went on Vacation for a week, parents tried to fix while i was gone...hahaha.. they added clarifier and blue sheen or something, didn't work, when i returned home it was a dark green again. Added 1 32 oz bottle of metal out. Vacuumed several times, let paper filter run, clean/changed filter, for a week...Now back to "PRO", said i need sand filter. So 2 days ago, got a 1hp 16" sand filter, been running for 2 days now. I can see the 3rd step on the ladder but the last one is another story. i've brushed and mixed it up hoping the sand filter would clear it up. I added another bottle of "metal out" last night. Had water tested, here are results, using Walmart/Lowes chemicals, baking soda and 3" chlorine tabs.
free chlorine 7.0
TC 7.0
ph 7.4
Hardness 330ppm
Alk 100 (it was 17, but added 12 lbs of baking soda to raise it)
CA 10
copper .25 ppm
IRON .42
i NEED SOME HELP, MY BOY WANTS TO DIVE FOR THINGS AND HE CAN'T SEE THEM TO DIVE FOR THEM... We have been swimming, but it's hard to invite people over to a green pool!

i have read a lot of your posts about needing more metal out so i ordered some last night, it should be here monday hopefully..i hope that is what i need to do... more metal out with high chlorine level, low ph, let new sand filter run....
