HELP with Green/Brown Water

[poolrookie]

Thanks for the reply, i think why the water cleared so quickly was the 10lbs of iron out, because all i did before that is shock it... i didn't add any metal stuff until i returned back from vacation and the water was back to dark green. I did have the water computer tested, that is where i came up with all the number.. my dad now tells me that while we were gone they tried something called, "Green to Blue" i guess it supposed to turn pitiful green water to pretty blue.. he put it in and let it run for 4 hours or so then turned the pool off and let it sit over night, pool is clear when we do that and all the brown is on the bottom until he tried to vacuum it up and then it just mixed the dust up and got all cloudy and green again. I guess that must be some kind of floc or something... So now that we have a sand filter, should i turn it off, it's only been running for 48 hours now and it's still light green... or will it be better to keep it running and let the filter work or try and vacuum it out in the morning? i have done both in the last week, but just don't know what to do next?? So you think ihave algae now??? how is that possible with shocking the pool so much, i know before i left on vacation i shocked it like 5 times, before i went with the iron out?? then took a reading and it was so high up the charts i thought there was no way to have any algae at all...it was dark red on the chlorine reading.. i have put 4 or so ounces of algaecide in yesterday and a couple of days ago and some a few days before that also... should i add anything else to the water???? metal free?? or just let the filter work for another day or so and check it out or shut it down and try to vacuum in the morning??? this has been so aggrevating... The chlorine is already high, because i shocked it this morning again, and i just went out and put 2 trichlor tabs in the skimmer just before the sand filter to maybe help get some iron out.... WHAT ELSE TO DO, JUST WAIT???
