What can I do for cloudy greenish water

your alkalinity is way too high. It shouldn't be above 7.8... 7.4 - 7.6 is ideal. I use muriatic acid to lower my ph. Also, your alkalinity is too high. should be between 80 and 120.
There is a sequestering agent you can use to try and drop the metals out of the water, if any are present. You stated you had high iron.
However, before tackling the iron, you need to get your ph under control. Chances are if you get your ph and alkalinity in line, your water will look a whole lot better.
If it is still cloudy, I would use a floc product.

first balance the pH and then test other chemicals BALANCE pH FIRST. and rum pump continuously for a few days. and then about 8 hrs a day.

While your problems are likely greater than just the salt content in the water I can tell you that if you feel, or more importantly can taste the salt in the water your salt level is WAY TO HIGH, not low. Have the salt level confirmed with an independent test either at a pool store or using a salt tester.

Did you try shocking it ?

what you are smelling is clormines check free clorine level this smell usually comes from not having enough clorine in pool smells just like clorine

not enough info like what kind of chlorine and if salt water set up Cloudy water is usually not enough filtering or low chlorine for an extended period of time Be more specific.

No matter what method salt or regular water you need to turn the pool water over at least 3 times a day/night

Lets use generic #'s if you have a 4000gl pool and a 2000gph pump you need to filter at least 6 hours you will need to adjust the #'s for you and figure out how long to filter.

It is also important to keep the chlorine between 1.0 and 1.5 then set your ph level with either ph up or ph down depending on what yours registers at after the chlorine is set.

Remeber that you must first set the chlorine since the ph is affected by chlorine level.

once both are set then the ph will go up and down with your chlorine so keep it in check after initial setting

for now add a little extra chlorine and filter for 24 hours then vaccum remeber to take out the filter cartridge once or twice a week and hose it hard with the garden hose. I am on my 3rd season with the same cartridge

start with testing your chlorine and ph add liquid shock and conditioner to water dont use algecide you have to get clorine to open up this is critical ph clorine and conditioner you should get a good clorine reading or you have to add more shock

Chlorine generator systems gradual increase the water's pH. You'll need to add acid to keep the pH down around 7.4. High pH can lead to cloudy water so get the pH balanced and you should be ok.
